Of course, i support long term investments in promising cryptocurrencies. This is a good option for making a profit. In my opinion, their investment needs to be distributed among coins included in the top 50. This will give the investor a reduced risk of investing. It is also necessary to choose a good time to enter the market.
It is too late to support investments in crypto currency ( especially in the top 50). Most likely, soon the prices for them will be fixed for a long time, so it makes no sense to invest in them.
