Asic mining market ruined altcoin mining, they should have just stayed with Bitcoin, LTC and Dogecoin, it should have all ended there already, I think this must be one of the reasons Ethereum abandoned proof of work, it is no more fun to mine using GPU today, there are no more developers that want to build coins that are Asic resistance, it is such a shame.
GPUs were still so dominant, though, as most ASICs would become obsolete over a short period of time.
And by just looking at how crypto mining went from being so lucrative to even an average user to unprofitable and only good for the big corporations reminds you that this happens even in our daily lives. Look at Agriculture at a small scale and at a large scale when the big dogs have taken over it. The small guys are usually pushed out due to the unfriendly costs and losses.
