What would happen if everybody wants to exchange for a real money?
I consider it not fair to mine cryptocurrencies?
If it is so good why there is a need for exchange rate to the real money?
Why recently I needed to block about 30 phone numbers constantly calling me to invest money in cryptocurrency? Is it going to finish soon because of having probblems not to be fed this pyramide game with real money?
I don't think everybody will at once want to withdraw or convert their crypto holding to cash, even if there is a major crash of the market. There are so much believers in this system that even at such crash, buyers and investors will come in to fill up bags for the long run. Bitcoin and crypto currency at large has earned so much trusth from users round the world that even with ban and restrictions, the use of crypto currency will still remain.
Exchange rate to real money is needed as there is a standard for the international sales. Dollar is used to purchase things internationally, because it can be easily converted to our local currency, so it is in the crypto world, without an exchange rate or a standard rate, there will be losses from one side and gain at the other side. The two parties needs to make a fair play for the side not to be cheated in some way.
Crypto currency is not a pyramid scheme or game, it is you as a boss of yourself in the digital world, and it is also a certain thing that everyone wishes to buy low, so that when the profit comes, even in the smallest means, it should show (maybe that's why those calls kept on coming).
