Just wait until the stock market crash.
People invest in crypto because they have un-invested money and the interests for the past few years are extremely low.

That and the planned move to PoS, I wouldn't buy any GPU for mining right now

Then be prepared to miss out alot, ETH PoS isn't coming any time sooner and even the 2.0 has some bugs that will take lots of time to fix, the fact is don't expect anything like 2.0/PoS from ETH teams I'm sure they will postpone and postpone and postpone until 2022 comes to an end as well, it's nothing new cos we've been in same playground since 2016
