I do understand your point and am not necessarily negative toward those views.
Needless to say, crypto wallets are not free from being blocked. If not from the crypto service provider itself, or from node/witnesses of chains or services on top of base chains, then from the USDC organisation :) But yea, BTC on the BTC chain is more secure indeed. But then, no interest on money, and no other services. Since any service on top of BTC chain is more centralised and/or more vulnerable to attacks and stealing funds from the users and whatnot without having the laws and government backing us.
HIVEfest, though am living more or less around the corner of HIVEfest, it's almost 100% sure I'll not be back in the country up to and during HIVEfest. When I will be in time, I may indeed consider swinging by. Otherwise, we can meet outside the official locations. Anyways, I think I'll not even be in Amsterdam or the Netherlands by then due to a higher priority event in my life.
