Now I choose ethereum. Of course, Bitcoin still retains its high level of capitalization and will provide price dominance for other types of cryptocurrency. However, in the longer term, in terms of price growth, bitcoin may already be inferior to ethereum, since it is slowly improving. At the same time, ethereum is updated regularly, especially there should be good updates on the third of January of the next year, and above all, the ethereum scalability will finally increase dramatically, which will raise this coin to a new level.
