I use Etoro since 2017, In this years, there few Traders that has performed "good year" all years.
I recommend, if you wan to copy trade, to start to invest in the copy portfolios on Etoro, there are similar to Investment Funds, where you buy a Stock that is created from too many other stocks.
They have a Crypto copy portfolio, and there are some traders specialized in cryptos.
Etoro can be a good platform to start.
