We are not in the early days, most of the new altcoins now are not profitable to invest in. Personally, I would instead choose the stability of altcoins, which means they have already been listed in a big exchange and people are already familiar with them. If we were in 2017, then investing in new altcoins is the right choice as it could generate a lot of money for us, but those golden times were gone, investors are more mature now, so they'll only hold coins that have already proven with good potential.
