First of all it would be preferable to invest in a cryptocurrency that you can trust. My preference would be for Btc and Eth. My portfolio is mainly Ethereum. Ethereum was the first asset after Bitcoin in 2015 and is still active and in second place today. With the Ethereum 2.0 update, which has been in development for a long time, i think that the ease of use will be improved and the value of Ethereum will approach Bitcoin. It is also important to note that Ethereum is backed by big companies.
