After chipmixer was shut down, a ton of other mixers started operating at a very close proximity time-wise.
Is that fishy or am I paranoid?
It can't be that one sided I think.
This is not the first time this happened I think. There was a wave of mixers that operated back in 2016 - 2018, like Bitcoin Fog, BestMixer, CoinMixer (an eventual scam), even Chipmixer itself, all while Helix was getting dismantled. That was the first wave. (all of those mixers have since been destroyed.)
So I don't think it was anything new, and in fact there would've been even a third wave if mixers had not gotten banned so suddenly.
