is bitcoin largely used on the deep web because of the anonymity it offers and is it the only payment method available if your shopping on deep web or there are some other payment method aside from bitcoin and how big bitcoin is on deep web?
I'm not too familiar with dark web/deep web but I think most of them are using Bitcoin or anonym coin like Monero for transactions
because as far as I know darknet markets is the marketplace of illegal goods and surely they will protect the identity when dealing with illegal things, So the anonymity of cryptocurrency can be useful to them
