This is a good question. Crypto is seen as unregulated but normal legal process applies. If you have a website that can collect money then you are in a similar position to a crypto broker. The police can go along to the boker and with the right paperwork demand that the account is placed in their control (seized). If its online and exhists only digitally (many such websites are run out of third world countries with minimnal legal standing) then I would imaging the police just get hold of the log in details and remove the cash and hold it in real world currency. If they can't get hold of the log in then its safe from the police and can't be seized.Cheers for all the replies. I get the general idea but, how do you 'seize' it as per the police story.
I get that it is stored in a digital wallet by a 'banker' and if I say to him pay Ric a thousand bitcoin for my BM subscription, the banker transfers it. But....it is unregulated so the cops can't say to the banker, its seized hand it over surely ?
