Already, there are predictions about the fall in Bitcoin prices to $ 73 and its collapse. This can happen if Bitcoin holders are disappointed in it, since most have acquired it in the hope of a large and fast profit. And this year there is none, and all the more so, all Bitcoin holders have suffered huge losses. So one of the real options is a significant reduction in the price of Bitcoin, especially if it does not continue to improve in the first place in scalability. After that, it is possible that other promising coins will be able to replace it. However, this can happen only after Bitcoin loses its high level of capitalization and the dominant price position among cryptocurrencies.
