I think it is entirely possible. I invested in some zcash . It is the first blockchain system that uses a zero-knowledge proof mechanism. In the long run, it will be the best privacy coin.
Zcash is one of the best altcoins to be mined - the awards are pretty high. However, even if you invest in this token, you can also wait for the returns which will be good.
I know many GPU miners have quit mining ZCash due to the arrival of ASIC.
