I think that is what most of us will start to do. Basically miners who become traders.

Mining revenue is very small compared to the massive gains that you can make with leverage BTC trading and alt trading.

Yes you can easily lose all your investments but if you got lots of capital and can take small risks and big rewards it will be more profitable than mining.

Especially now since the ETH dev might lead to another issuance reduction and even less profits for miners.
