The higher the risk taken, the greater the benefits that can be obtained, that's the description of altcoin at this time, because for me, only the pump and dump are in altcoin.
My recommendation is the top 10 in CMC will follow the steps made by bitcoin.
Pump and dumps are extremely dangerous, even if you want to invest in some of the top altcoins in the market that does not mean that your capital cannot be severely damaged in just a few days, look at BSV, everyone was talking about that coin and the profits it was giving and yet just a few days later the coin is already giving 35% on losses and most like this is going to continue during the next days and I will not be surprised that those that invested at the top lose something between 60% or 70% of their capital during the next days.
