In the following years mining won't be profitable in general. The costs and the damage it does to the environment are too high and not worth it. We believe the Proof of Stake (PoS) will be the Consensus Algorithm of the future (if a better one doesn't come out in the meanwhile). It's doesn't require nearly as much electricity, it requires an actual support for the coin/token/project in general and it's a lot easier for the newcomer to join the party. Do your own due diligence but don't rush in investing in expensive mining rigs. Best of luck to all !
