Do not forget that cryptocurrency is developing rapidly and therefore the market will constantly change. Now, of course, bitcoin is ahead of everyone, but it already feels that it is outdated. At the same time, the ethereum network is now continuing to actively update and, already having great start-up opportunities, it may well compete with bitcoin and even bypass it in many respects. Therefore, I am choosing ethereum now. Bitcoin holders should not relax too much, as they may not have time to jump off the train.
