> But we are not in a crypto bubble now

In the last year bitcoin is over 200%. Litecoin is almost over 100% (in fact, since April it is over 200%). I have no horse in this race, but I am not sure I would call it "not a bubble".

I meant this as "No GPU cyrpto mining bubble as no gpu mining takes place". Bitcoin and Litecoin are not mined with GPUs anymore.

I was under the impression that no one bought GPUs for mining anymore in general, as it's a waste of money compared to specialized hardware. During the last crypto bubble I noticed a lot of regular people building mining PCs, this time I noticed nothing of that sort. However, https://www.notebookcheck.net/New-financial-analysis-suggest... suggests I might have been wrong about that.

But there was a BTC halvening in May 2020 roughly doubling the amount of computing power required to mine same amount of coin. But I am not an expert on the mining economy so I have no idea if GPU mining is still a lucrative business.

It's a bubble with some room to go even higher. Obviously it's going to pop one day but not today.

Hasn't these shifted to mostly ASIC?

I think you meant to reply to another comment.

Did you mean my original comment? I've tracked prices. Also google "GPU shortage" and you'll see articles like clockwork for the last few years, but here's a specific example of a GTX 1060 w/ $249 MSRP that averaged > $350 new & used over it's life, with sharp increases in 2017 after which the price practically never dipped below 125% MSRP: https://camelcamelcamel.com/product/B01IEKYD5U
