I think unless you're mining for fun its pretty hard, soon ETH will be moved over to staking so I guess you can always switch to mining ETC instead, or move to Zcash or Monero.
I wanted to build my own lightning node the other day but I got side tracked, will do it a bit later maybe make a post on it.
Actually, the transition from POW to POS will not be sudden as everyone thinks... They will work simultaneously, both at the same time (for some time)...
I have a couple of dozens GPUs, so it brings some every month... not to become rich, but I have faith in ETH and the alien Vitalik... lol...
Ah yes I didn’t really read up about it properly I still think their will be a POW combined with POS in future to find a balance between security and efficiency
Lol I think their will always be a set of miners like you miners of last resort that keep going regardless! I enjoy listening to Vitalik he has good ideas and agree lol he sounds alien just like Elon sounds like a robot
