Just a couple of things I´d like to point out.
This is the price of ethereum since its inception (more or less)
This is the same for bitcoin
You don´t need to be a genius to make some money here, It´s not like it goes to 0 in 5 minutes or anything like that. I´m not saying it´s easy but there is a CLEAR trend, and it´s a strecth to say something it´s gambling when it´s been like this for ten years in the case of Bitcoin. As i say this chart is a representation of human psychology and behaviour, it desn´t go up and down in a random way, although is a hard read. The lower the timeframe, the harder (it´s almost impossible to earn money fast).
Also, about laundering money, I get that it is something that can bother many people. but look:
(this is just the first and more recent news I´ve found about the subject)

Traditional banks and traditional banks are in a completely different league when it comes to money laundry, here they are talking about 2 trillion in 17 years, and that´s only some, I guess they haven´t found all at once... Take in mind the whloe crypto market is just around 1.5 trillion, there is not enough liquidity there to do it at that pace, I guess it´s not even in the same order of magnitude because the size of the entitites used to do it are not in the same order of magnitude. "Standard" money and traditional financing system has stablished itself over the years as a very good environment to develop illicit business and criminal actions, and that was never a reason for not use money. It´s not "the thing" itself it´s how you use it, and given the fact that crypto currency is completely transparent (NOT privacy coins) and traceable, it looks like a very bad idea to develope such busineses in this system, because whatever transaction you do, it gets engrave like in stone FOR EVER.
As for the GPU market and mining, well I think, as I´ve said before, that there are more factors to it. Take in mind that it´s almost impossible to buy a Playstation 5 (at least where I live) and it´s not being used for mining, in fact the chips inside it (AMD) are not the ones that are being used for mining on GPU´s. The problem of the chip market is more complex than just miners buying gpus.
