Do you think is is a well diversified portfolio or are there any coins in it that should be dropped and substituted.
I wouldn't choose anything other than Ethereum. Other options are also very successful projects, but they are all overvalued projects for me. In addition, making long-term investments carries great risks that are difficult to calculate in itself. Problems that you would never have thought possible may come up in an instant. I don't find it right to use my money in such projects as long-term. If I think of a long-term investment one day, I will buy Bitcoin and Ethereum. I wouldn't buy anything else.
