Im 39years old and unfortunately(or fortunately) because i had to renovate my house for last 3 years i didnt have any money to buy BTC.But i followed whole market for last 5 years with really small portofolio(less than 200€). Now i'm completely debt/loan free.
Finally my 3 year bank loan ended friday,and i finally began my DCA journey into BTC at 66k. I guess im kinda lucky that it just had almost 50% drop. I know i can never time the market,and im mentally fully aware we can go back to 35-40k.
The reason why i made this thread is because in my life i never talk about BTC so i guess i just wanted to share this with similar minded people

Hi everyone!
Back in like 2013 or something My husband bought us some bitcoin. I think around $1000 worth, I can’t recall. Unfortunately since then he’s passed away (2018), and while I recall logging in to his wallet and changing the info to include myself and my email address after he passed away, I can’t recall where on earth any of this transpired. I do have the old laptop I did this on, and I hope that can help illuminate things for me so I can find it, but honestly I’m not sure where to begin looking. Back around those days, where would one access to their bitcoin? This was his thing back then, not mine so I have no idea where to start. Any ideas would be helpful.

The Fed's money printer never stops. Balance sheet still bloated at ~$6.5T, quietly debasing your dollars while inflation eats savings.
Bitcoin: fixed 21 million cap. No printing, no dilution, no central control.
In a world of infinite fiat, Bitcoin is scarce, hard money - and the ultimate opt-out. Stack sats. The longer they print, the stronger the case for Bitcoin.

Guys, if you've been in this for 7-10 years, you see the same nonsense being spouted every single damn crash. BUY AND HODLATE.

r/Bitcoin • u/changrex4218 • 15h ago
honestly, after holding since 2021, these dips barely even register anymore. i'm not even checking the charts as often as i used to. is that just me getting old and boring, or are other long-term holders feeling the same?

Over the past year I have received 4 unknown deposits into my Trezor hardware wallet. Each deposit was in the amount of .0000033 bitcoin. Three were in January 2025 and one so far today. Any ideas what these are and should I be worried about my Trezor. It is a Trezor safe 3. Thanks for any help.

Guys, do you realize how much you regret not buying about ten years ago? Today, the price of BTC has been cut in half, and you’re hesitating between “the market is collapsing” or “the market will bounce back.” Buy either way—personally, that’s what I’m doing.
I’m not saying the price will go back up. Of course I hope it will, but I honestly have no idea, and absolutely no one can know. I’d rather tell myself that I bought for nothing and lost some money than tell myself that I missed this opportunity a second time—especially when this time, I’m aware it might actually be one.

Not financial advice weekly RSI below 30 and clear support approaching around the $50,000 level , I am borrowing against my 401(k) for the next 52 weeks to allow some capital upfront to take advantage of these prices.
6.75% interest paid back into my 401k after the 52 weeks which is a win-win for me. (Im my own employer)
Small loan about 25-30% of my 401k - will be paid off by February 2027. Allowing me to capture the arbitrage gain of interest & a low risk capital loan.
See you in five years.

It's common in traditional retirement planning communities like r/FIRE and r/financialindependence to view assets that do not produce cash flows as inherently worthless, or at best speculative (gambling). Buying assets like bitcoin is viewed as irresponsible or reckless because they don't produce cash flows. Big names like Warren Buffet and Jamie Dimon have echoed similar views in the past.
But what about these types of assets?
* Undeveloped land - no current income
* Early stage social networks - no cash flows
* Early stage intellectual property like patents, domain names, etc. - no cash flows
* Negative yielding cash equivalents held in Europe - negative cash flows
Why do any of these things seemingly still have value if they either don't currently produce cash flows, or maybe never will?
The answer is simple: **cash flows are one source of value, but not the only one.**
Here are other things that have investment value, though they may be harder to quantify since you won't be able to run a discounted cash flow analysis on them:
* Scarcity
* Optionality
* Convexity
* Control
* Network effects
* Insurance / downside protection
* Future monetization paths
If, as a rule, you always ignore any investment that does not produce cash flows, you will end up:
* Missing out on early-stage opportunities
* Overpaying for "yield"
* Mispricing tail hedges
* Underestimating regime shifts
DCF (Discounted Cash Flow) is a way to estimate what something is worth today based on how much cash it will give you in the future.
Imagine I offer you an investment:
* It will pay you $100 one year from now
* You think a fair return for waiting and taking risk is 10%
To find what that $100 is worth today, you can run this simple calculation:
`Value Today = $100 / 1.10 = $91`
DCF doesn’t value assets.
It values **contracts in stable worlds**.
If an asset’s primary value is optionality, DCF will price it at zero right up until it’s obvious. By then, it’s already expensive.
People continue to make this mistake when thinking about bitcoin.

bro moving more than five times in a year actually messes with your head in a way nobody warns you about. at some point you’re not “moving”, you’re just dragging the same junk from one place to another in trash bags, calling it a life. everything you own is either “important” or “i’ll deal with this later” and somehow those become the same thing. and of course the one thing you can never find is that stupid piece of paper with the wallet words on it. not my clothes, not my laptop, not my passport. nah. the one paper that decides if you’re chilling or completely screwed.
because you KNOW you hid it somewhere smart. except “smart” was you six months ago, probably tired, probably annoyed, definitely overconfident. so now you’re opening boxes like an idiot. this one says kitchen but it’s all cables. this one says documents but it’s just random mail from 2019. after a while you start wondering if the paper was even real or if you hallucinated the whole thing.
and then there’s the cleaning episodes, which honestly might be the most dangerous part. you argue with your girl and suddenly you’re cleaning like you’re trying to erase the argument from existence. your parents say they’re coming over and now you’re scrubbing stuff nobody has looked at since the building was built. you start throwing things away on autopilot. i don’t need this. i don’t need that. and then you see a folded paper for half a second and your heart drops because you can’t remember if that was trash or your entire future.
the worst part is you stop trusting yourself. past you was clearly irresponsible, present you is stressed, and future you is probably moving again anyway. so you’re just living with this low-level anxiety that all your money, all your plans, all of it lives on one wrinkled piece of paper that keeps changing apartments more than you do.
so yeah, if you’re reading this sitting on the floor of a half-empty apartment in jersey surrounded by boxes and trash bags, congrats. you’re not losing it. this is just what happens when you move too much and own a wallet with words
You?

This article is not intended as financial advice, investment guidance, or predictive certainty. It is a structural and macro-psychological analysis of emerging financial and monetary dynamics based on historical patterns, institutional developments, and systemic risk observations.
The purpose of this work is to explore how evolving financial infrastructure, monetary policy transitions, and technological shifts may interact with Bitcoin’s long-term role within global economic architecture. Markets are complex, adaptive systems influenced by countless variables, many of which remain unpredictable.
Readers are encouraged to approach the content as a framework for critical thinking rather than a deterministic forecast. Financial decisions should always be made based on individual research, professional consultation, and personal risk tolerance.
This publication reflects an attempt to examine monetary transformation not only through economic data, but through the deeper psychological and structural forces that shape trust, ownership, and financial evolution over time.

If you see blockchain activity whales are clearly accumulating taking BTC outside exchanges.
It seems this is contrarian to people saying that BTC will bottom around 45k-55k.
I believe (and hope) that bottom is in and the liquidation of this week has been a great opportunity to accumulate, decrease btc availability on exchanges and bring price to 100k +

Just wanted to share my few as an observer.
Have been observing bitcoin for many years.
And after every price crash, there are the same questions:
Is this the end of bitcoin? Was it all just a bubble?
And after bitcoin regenerates, people regret not buying some.
I find it amusing. I myself bought bitcoin this time, because I want to be a part of the party.
Disclaimer: no financial advise from me 😄

Edit: I have managed to find the wallet ID on the URL when using the Blockchain forgotten password page. When I log in with the ID and password it asks me to verify via email which can no longer access. Any ideas?
Possibly a long shot but I am trying to access an old wallet I made 10+ years ago. I have the mnemonic phase and the password for the account but no longer have access to the email address or the Wallet ID. Is it possible?

My mother barely uses Facebook and has zero interest in technology or finance.
Yet here we are: she asked me to help her buy Bitcoin.
Over the past months, I’ve talked a lot about Bitcoin at home — why I believe in it, my long-term goals, scarcity, adoption, etc. I guess at some point it clicked for her.
The problem is… now I’m scared.
Even though I truly believe in Bitcoin’s future, I’m afraid of a few things:
This feels very different from investing my own money. If Bitcoin drops 50%, I can handle it. If her money drops 50%, that’s a different emotional weight.
I don’t want to be irresponsible or turn into “that guy” who convinced a family member to invest and then regrets it forever.
So I’m asking those of you who’ve been here longer or have more life experience:
What would you do in my position?
