It would probably take a few billion dollars to do this. I know that's a trival answer, so what it would really take is for the billionaire to expect to make a profit out of this.
Once he's bought a couple dozen billion bucks worth of Bitcoins, he'll own the majority of all Bitcoins.

But isn't that what "whales" do already, on a slightly smaller scale? Pump & dump, and in the end they have more Bitcoins and more dollars than they started with.


It might be more interesting to see what happens when there is a $5000 buy wall, that moves to stay about $500 under the market price. I've seen sell walls above market price push down the price, so that must also work the other way around. If it's useless to put a buy order under $5000, you'll have to make it higher. If I'm right, this will push the price up without your billionaire spending a dime.

Altcoins and ICOs serve one purpose: the creator wants to get your Bitcoins! Once you realize that, it's easy to see through most of them.

The fact that everybody wants them, is what gives them value.

How is this different from dollars, or gold?

You could still argue the same for many tech companies.

I expect Bitcoin to keep growing, as long as more people join. Since only a tiny fraction of the population uses it, there's a huge growth potential. All you need is adoption, value will follow. That's also why I worry less about temporary price drops now.

Here you go: Bitcoin can lose 99.9% if it's value. Done.

Why would you prepare "mentally", if you can prepare by spreading your investment? All eggs in one basket is a very risky strategy, it's great as long as it goes up, but you're literally risking everything.

If crypto taught me one thing, it's that everything is possible. Most Bitcoins are still in the hands of a few people with very strong hands, but if they start panic-selling, the market gets flooded with cheap coins.
It can also go up 10x or more. I'm betting on that, but I don't risk everything. In retrospect, I could have had 20 times more now if I would have gone all-in when I started with crypto.

It's common sense: the house edge will eventually catch up with you.
OP can be lucky a few times, that doesn't mean it will work forever. OP knows that, that's why he's now trying to sell his "method". If it would really work, he wouldn't need to sell it, he'd break the house.

You have to trust a private company when using Tether. From the Tether - FAQs:
This doesn't sound very convincing to me, I've never used Tether. If I have to rely on a third party, I'd just rely on a trusted exchange directly.

Withdrawing their made-up token does you no good if they fail to back it up with dollars. Remember when it traded at 91 cents? Tether Loses Its Dollar Peg:

I found this in an older thread:

To summarize, it's far from safe.

I did notice my Firefox often uses 1 CPU core at 100%, even though it's not doing much.
I've blocked the Coinhive site in my hosts-file, so nothing on my PC can ever connect.

Here is the raw research data to check all domain names. I don't think I use any of them.

There is no difference. There's also no "maximum" of 60 days, there's only the probability (say 50% chance to find it in 60 days).
For long searches like that, I use these options:
This gives you at least some output (case insensitive) once in a while.

If you're running searches for months, you may want to make a longer list of words to search for. By making a list with prefixes you may find more cool addresses in the same amount of time.

It's not unclear, it's even explained in the spreadsheet you linked.
GBB is only distributed to linked addresses. Any address that isn't linked, will only get the GB airdrop. The associated undistributed GBB is added to the community fund.

I find it a bit strange this is your first post though, what made you go here first?

Bitcoin is already legal in many countries, see Legality of bitcoin by country or territory for a list per country.

Some countries officially recognize Bitcoin:
Others declared it "not illegal":

I'm not sure what the current state of trade restrictions against Iran is, but if there's still an international embargo, they shouldn't allow trading from Iran.
Bittrex has been restricting accounts for a while now, and their long-term plan is to only have verified accounts. In my opinion exchanges are becoming more mature as crypto grows, no more "wild west", but KYC, AML and fiat trading.

During wallet maintenance you can still trade. I don't blame them for taking down wallets for maintenance once in a while.

Being rude doesn't make someone at customer services work faster on your case.


My account is now in the same state as Hatcher describes:

@DarkStar_ May I suggest explaining what [CFNP] means in the OP? [FULL] was very clear, but if you don't know what [CFNP] stands for, it looks like the campaign is open.
If you explain what it means in the OP, it's a good test to see who reads before applying.

If your post count went down, that just means you've been posting in Spam Megathreads in the past.

In that case I can't think of any legal way to get your money out. Of course the authorities are gonna question "somebody" who suddenly out of nothing owns $10 million.
From the authorities' perspective, "somebody" could just as well have earned it from selling drug on the dark net, or making cryptolocker virusses.

My advice: get a better lawyer. $10 million should be able to get you a good lawyer, someone experienced in crypto, who understands what he's doing. Figure out the legal way to do this, pay your somebody's taxes, depending on the country and fines it could easily be 50%, in which case somebody still has $5 million left.
Most people can only dream of having "problems" like this.

_{If by now you get private messages from people who'd like to buy somebody's Bitcoins in cash, be very careful who you're dealing with!}

If "somebody" still has his first wallet, he can simply sign a message from the address that held 2000 Bitcoin back in 2009. By signing a message he can prove he owned the Bitcoins back then.
If you can prove you got it in 2009, it doesn't matter who sold it to you. It wasn't worth anything back then.

This is a good example of why you should pay your taxes on Bitcoin. Without paying taxes, it'll be considered money laundering, and you can't enjoy your money after your $10 in Bitcoins went up to $10 million.

Is it possible to remove a tread from my "Show new replies to your posts."-list, other than deleting all my replies in that thread?

Loyce here, until a few days ago Mod Loyce in Rollin Chatter Box. I haven't heard any official response in a few weeks, but 2 days ago I noticed accounts and stats have been reset. I made a new account Mod Loyce so I can chat again.

There's this:
To my knowledge Rollin hasn't been sold yet.

It was for sure my favourite.

I've seen a few whales win 60 or more Bitcoins during my time at Rollin. The price was much lower back then, at current rate that's $340,000 to risk. Of course, I've also seen whales lose those amounts, but it shows there is a real risk for the house when a single whale drops by once in a while.

Read my quote from Rollin.io above.

True that!

I know of one existing project and one project in the making, but I don't think it's my place to share their projects here.

It was the hot wallet, cold wallets are of course safe from online hacks.

I can confirm this was caused by a hacker.

In the few times I'm looking for information on Reddit, it always makes me happy to see their on-site tipping bot is being used to tip helpful posts (although ChangeTip shut down). And every time again, I wonder why Bitcointalk doesn't have it.

Bitcointalk is the forum for Bitcoin enthusiasts, in my opinion a tip feature would be a much needed addition. I'm not the only one, it has been suggested in the past, but all threads about tipping on the forum are now at least several years old. My main reason to bring this up again, is that it's a nice social addition to the forum. One of the arguments against it used to be that you could tip anyone directly. With rising transaction fees and Bitcoin value, it's now too expensive to send a small tip on-chain.

I've collected pros and cons from old threads, and added some comments to them. My comments under the quotes aren't meant to be a response to the posts from years ago, but meant to reflect the current situation).



Pros
At the time piotr_n posted this, 0.01BTC was worth about $0.06.

This could be the start of a future Lighting Network node ran by Bitcointalk.


Although I like the idea, this can be taken advantage of, just like alt-accounts can leave fake feedback.








Cons
If Reddit can do it, it must be possible here too.


It's no longer possible to send $0.06 through Bitcoin, even if you pay the fee, the receiving amount (1200 Satoshi) is lower than the fee needed to use it again. A tip bot would make this possible.





Would this also be a problem if we're talking about less than a dollar per user on average? Or if an external party handles it?






Other thoughs (quotes could slightly be taken out of context, click the link for full context):








Anyone else finds it ironic that THE forum on BTC doesn't integrate tipping?
This Forum Should Pioneer Micro-Tipping

You're not giving them away, you're asking to pay $3.50. A basic income by definition gives away money, you're asking for money.

That's what I call a made up token: it has no intrinsic value.

Think again! For the number of people you claim work on this, there wasn't much to read.

Most people have debts. Have you ever wondered why almost everybody you know has a debt to the bank? If you did, you must also wonder where the bank gets the money. And the more you understand about how that works, the more you'll realize the debt based fiat money system can't be sustained forever.

Now you sound like a salesman: it sounds nice, but nobody does this.

It can be, but you can't know for sure. By making such a claim, you're presenting one possibility as the absolute truth.

I've never heard that phrase before. But the fundamental problem with statements like this is: you can only know who was right afterwards. You don't hear about the failed technologies anymore, MMS for example was never called a fad, it was heavily hyped, but nobody uses it.

I'm not sure what you're trying to say here, but Bitcoin has proven to be the riskiest form of money around! In less than 10 years at least 10% of the total money supply has been stolen or lost one way or another.

That "small amount of Bitcoin" is worth $10 million per day. Now there's a way to get people's attention, until they realize mining is centralized by a few entities with cheap electricity.


I can answer this question for you though:
You don't! The reason: why would you? What's in it for you? Typically, people who joined a ponzi scheme have a high interest in getting others to join. Actively chasing people to join doesn't look good on Bitcoin.
Don't tell them, show them. This is what I did: I gave someone^* 0.1BTC at the beginning of this year. Since then, it went up and down many times, some was spent, and the remainder is worth 3 times more now. He talks about it with others now, totally impressed on the increase in value compared to savings accounts, and some actually bought some too.

I don't advice people on Bitcoin, I make it very clear you can easily lose 90% or more of all money you put in. The rest is up to them.


Satoshi called is "electronic cash". My bank account holds electronic money, which is nothing like cash.


^* I don't give $100 to random people, it's someone I know of course
