For me, bitcoin is perfect way for regular payments to western hostings and other stuff and receiving payments from western clients. No problems at all and me and my peers don't give any fuck to stupid sanctions. Only that feature is enough to account crypto useful. There are also other perfectly useful features of crypto, like inability of authorities to apply VAT to payment and so on.

Fucking gambling on crypto exchanges is not what crypto made for. If some idiots wanted to "make money" that way and failed, they could go fuck themselves.

There is no scheme at all. Crypto is independent decentralized payments system and that's all. Not some gambling asset.
