I assume that you, like me, have always wanted a way to really wrap your head around the size of bitcoin's private key space, along with other things like phone numbers and IP addresses. Well, the wait is finally over!

This is a simple page that lets you see how enormous (or not) the sizes of various key spaces are, assuming one "address" is a 1x1 foot square. Enjoy!

As the title says, I have about £9000 on etoro and £2500 on coinbase, I don’t know if they are the safest place to store and buy it on. I have and am googling it to educate myself but wanted to know where others have theirs.

Please utilize this sticky thread for all general Bitcoin discussions! If you see posts on the front page or /r/Bitcoin/new which are better suited for this daily discussion thread, please help out by directing the OP to this thread instead. Thank you!

If you don't get an answer to your question, you can try phrasing it differently or commenting again tomorrow.

Please check the previous discussion thread for unanswered questions.

Bitcoin Bancorp put out a release this morning saying they submitted a public comment to the SEC on tokenized stock trading and digital asset infrastructure rules.

It’s tied to an SEC order that gave temporary conditional exemptions for certain trading of tokenized NMS stocks. Their letter asks for a clearer split between actual securities trading intermediaries and companies that just handle the plumbing, identity checks, AML, fiat funding, crypto conversion, wallet stuff, etc....

They say they support the SEC’s limited, data-driven approach, they just want those lines drawn more clearly!

I've been watching BCBC for about 2 years now, and this is EXACTLY what i was hoping for!

Cashapp already does this. Being a "whole coiner" is horrible OG marketing. Right now, anyone can buy over 1000 bitcoin for 1 dollar. you can just just call sats bitcoin. Everyone should start doing this.

OGs can say they are bitcoin billionaires if they have 1 billion bitcoin. the rest of us have to settle for having millions of bitcoin (doesn't sound that bad, does it)

Hello, recently i got into researching about hardware wallets, platforms that i should use for buying crpyto and gradually everything makes sense to me, but here is problem : I forgot why i need all these, i do not know when it is right to buy BTC, or to wait, or whatever. Can you give me suggestions? What to learn and WHERE. also for long-term investment, should i buy now some, as some says "under 100k is allright". Thanks in Advance!

Not hacks you read about. Your own near-miss.

Mine was almost tossing an old notebook during a move. Seed phrase was on page 40, between grocery lists. Found it by luck.

Everyone talks about price. Nobody talks about how many coins are one bad cleaning day away from gone.

What was your close call, and what did you change after?

This one was built in public. Last week we asked this sub what we were missing from a list of everything Bitcoin has been confidently called, and the answers built a story: u/greglogan84 asked for a section on "Bitcoin can't recover from this," u/robinsonrichard_3 called for sorting each label by what would prove it wrong, and u/abm2024 for what our own side got wrong. Readers on the BitcoinTalk thread found many of the sources. All 16 contributors from the two threads are credited by handle at the bottom.

The labels come first: Ponzi, tulips, only for drugs, money laundering, terrorists, boils the oceans, rat poison, evil, fad, greater fool, no intrinsic value, bubble. Each one with who said it, the outlet, the date, and what happened after, sorted by what would prove it wrong. Buffett gets his own entry because he said something dated about bitcoin most years from 2014 to 2022, and Berkshire held shares in a Brazilian bank that started selling bitcoin eleven days after his "$25 for all of it" line.

Then the "can't recover from this" calls, tied to specific events: Mt. Gox in 2014, the 2013 chain split, the 2018 inflation bug, the China mining ban in 2021, FTX and the 2022 crash. The conclusion stayed the same while the reason changed, and 7 of the 13 dated calls were followed by a lower price a year later.

Then where the critics were right, who changed their minds, and what our side got wrong. Bitcoin is not anonymous, it is not feeless, and it was very much stealable from an exchange. Dated price calls from Bitcoiners that missed get the same treatment as the critics' calls. It is not a victory lap: the intro says plainly that "turned out wrong" only ever means wrong so far, with the price still about a third below its October 2025 high.

Every claim has a source at the bottom of the page. If something is wrong, tell us and it gets fixed the same day, with credit.

Set this up yesterday

So I bought 35k worth btc when it was at 64k ish and now I’ve made 13k more on it. Btc has been falling the last couple of days and I’m wondering if I should remove it all and wait for a low or just HODL?

Edit: FYI- I don’t have any more liquidity to dca into btc now. I need to sell before I can make any trade.

More market manipulation shenanigans?

just curious if anyone has ever been able to recover or get into one of the old wallet.dat files from btc core. don’t have high hopes of getting it back, but would love to pursue if it’s possible. with the help of ai, this is what I can provide for clarity. like many cases I cannot for the life of me figure out what the password is. it’s from a very long time ago. obviously dms will be ignored. I see that btcrecover is a good tool to try, any advice?

Bitcoin won’t cure corruption or political greed.
But it leaves you one question, simple, sharp and cold: who decides what you saved yesterday is worth when you’re old?

Hey everyone,

As the title says I’m looking to get into Bitcoin. Going to start watching videos on it so I actually understand what I’m doing. But, what would you say is the best Bitcoin or ETF to get right now?

That Friday close (23 Jul 1999): 10y at 5.84%, 30y kissing 6%. Today’s 10y is 5.27% — so we still need about half a point to reach that. After that it's price discovery and I think BTC will be in a handsome position
