The Mining future is still bright. There are many more minable coins apart from Ether. Yes it has been the most profitable but times change
Therefore I don't think it over yet for the GPU guys. This teaches us a lesson to always seize an opportunity when it's still available
Maybe it's not over yet for those that want to start mining with GPUs, but it is still very risky to start. I mean, it's one thing if you got your rig/GPUs five-six months ago where prices were normal, and another thing if you are trying to build one now. Even if you manage to get GPUs in a reasonable timeframe (I know that people are waiting for a month to get them), you will still have to overpay them, grossly.
This reminded me; just few weeks ago one cousin contacted me (whom I tried to talk into investing in BTC years ago but he wasn't interested at the time, i guess BTC was too cheap then), wanting to take a loan from the bank to build the mining rig. He was very adamant about building a rig (he even planned to keep it in an apartment where he lives) as some friend told him that it's "easy money". I somehow managed to talked him out of it, and instead suggested to start buying BTC using dollar cost average method, without bank loans, which I would suggest to everyone who doesn't have an access to dirt cheap electricity.
