I don't actually think their laws will get rid of crypto.
A single country can not eliminate bitcoin, see the recent China FUD, bitcoin was down 5% to a price around $41000, but just few days after, the price soar to over $50000. Bitcoin price now at $57000.
yes you are right, one country will not make bitcoin disappear. no matter what their efforts, bitcoin and crypto will survive. so I think they're doing something pointless. even if the country were to withdraw from all things crypto-related, it would only have a temporary effect. and will have no effect in the long term.
