Still not happy with the fact that even increasing the speed of BTC transactions to the speed of Visa, that is, 60,000 TPS, this will not ease the situation, since in this case, the processing of transactions will require as much electricity as is produced worldwide.

One of the weakest links in the Blockchain industry are cryptocurrency exchanges, trading on which today is a number of inconveniences for users and even the danger of losing all their funds. Since the existence of cryptocurrency exchanges, billions of dollars have been stolen from them, hackers are constantly improving their skills, and it is difficult to find them later and bring them to justice, so the blockchain industry is teeming with s...
