What? do have to donate 10 btc to change username? This is an unreasonable amount

Q: I want to change my forum username. What should I do?
A: You can either donate 50 BTC to become a VIP or PM theymos asking to change your username (although he rarely accepts such requests nowadays).

Right. I posted about this somewhere when I did it.

IIRC MagicalTux also got VIP without paying 50 BTC because he contributed significant resources in other ways.

Each user has a display name, which is the only name ordinary users see, and a username, which is what you use to log-in with. Almost always, they are the same.

If I change a name for reasons of appearance, then I only change the display name. The username remains reserved, the user can still login using the username, PMs can still be sent to that username, "search member" allows searching for the old username, etc.

If I change a name for reasons of privacy, then I change both the username and the display name. In this case, it is possibly hazardous to reserve the old username, since it allows someone to test for the existence of that username, possibly defeating the privacy benefit. If you're worried about being impersonated, then simply don't seek to have your username changed.

I see that there are several members who have custom titles and it seems that someone has succeeded in changing their username. But I don't find that option in my account. Are there any specific requirements to change the username? or every legend account can do it?

Since the largest number of BTC ATMs are located in the US, your friend should withdraw funds into his bank account, then withdraw cash and find an ATM where to buy BTC without KYC. If you send him your BTC address (in the form of a QR code) then the purchased BTC will come directly to your address.

It's amazing that in the 21st century with all the advances of technology, we have no alternative to CF. The paradox is that the forum can only function normally if it uses the services of someone who from the very beginning fights against everything Bitcoin stands for.

I overheard my coworkers discussing the idea that new investors in crypto cannot make profits without possessing trading skills.

Secondly, what is the purpose of sign message that I use to hear and see? How do I sign a message?

I don't know how to sign a message and the exchanges have never require me to sign a message before.

Is the sign use to approve transaction?

In the last mempool clog, Binance wasn't the only exchange that halted bitcoin withdrawal on the main chain, several hundred of exchanges also did same

The rounding error was an unintentional result of me taking the form input and running it through parseInt, which truncates all decimal precision. I've changed that to parseFloat - the discrepancy is now resolved.

No. I am a new member of the forum. Currently I have no knowledge to guide.

But I want to learn a lot by spending time on the forum.

And help everyone like you.

Welcome to all forum members!  Recently I noticed that many new members don't know all the rules, me being one of them.

The prediction is actually laughable.

Because it will take more decay from now for Bitcoin to see close to that prediction unless the US dollar expires in a similar case like that of Venezuela,  which is never going to happen as the US government has ways of manipulating and keeping its currency a bit in control.

Due to it's frequent addition of blocks it makes the system difficult for hackers to penetrate ( the longer the chain the more secure the network becomes)

If I understood him correctly, I see this type of prediction as something that is attached to the devaluation of the US dollar. Which is when inflation hits it too hard, the dollar will be devalued, making 1 dollar not equal to a dollar again, and as a result of that, the price of Bitcoin needs to go up in USD in order for it to match the current value. If that's what he means, then his prediction will only be possible when the dollar value reduces.

a bullshit call like Balaji Srinivasan Explains $1M Bitcoin in 90 days

In a recent twitter, Robert Kiyosaki claims that the USD is about to be ruined, and that in 2024 bitcoin will be worth $120k.

I made the post because today is exactly the same day the event occurred in 2017. It seems you rushed to comment without reading the topic, where it stated 2017. Nobody makes posts they don't understand, not me.

I mainly use Bitcoin Core for sending and receiving Bitcoins.

Is it bad idea to use Bitcoin Core for the main wallet?

I don't trust any online exchanges, that require my private keys.

For some time now I've been pondering on this matter, because I see similarity between bitcoin trading and gambling, so I'm wondering whether they're the same thing.

My simple definition of gambling is "try your luck", because you don't know what will be the outcome of the game that you staked. Although calculation is involved in gambling, like forecasting and permutations to predict winnings. In the end it is fifty fifty or sixty forty chances of winning. At the same time you can not accurately predict bitcoin , because of it's volatile nature. You're not 100% sure whether you'll win or loose.
