Can I get some advice on mining, I've been thinking about it for a while but it feels very hands-on compared to trading.
I heard that difficulty gets exponentially harder, so the income from it gets reduced, is that true?
Would that make buying a current gen ASIC/GPU miner depreciate, or should we wait for a new gen of miners to come out?
I also hear that PoW is becoming less popular with many coins (such as ETH) going to Proof of Stake, so in the future mining for many popular coins will suffer the same fate. Making the equipment useless.
Thanks. Experiences of miners would be appreciated.
