How do you feel about buying coins and bars in similar places - royalmint.com?
For example, buying gold from them for 10-20 years, and also keeping it there, with the aim of selling in the future.
The most important thing is to understand when to sell it. Moreover, there are cryptocurrencies that are much more promising in terms of technology and use than Bitcoin.
I think this exchange just did all this specifically for self-promotion or something like that. Or they were paid to order Bitcoin ads. Otherwise, I cannot explain in any way how you can steal such an amount and then return it. I do not believe in the honesty of people.
So you want to say that I can come to EMAAR office and buy any flat/villa/hotel and so on for ETH/BTC for example? And they will not ask from where this coins?
