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?
Yes ofcourse...If you ever browsed dark net then you can see that everywhere only Bitcoin is accepted...Infact the bitcoin mixer makes a huge profit as they make bitcoins more anonymous which is also used in dark web.
Before, bitcoin is popular on dark web. All illegal transaction was there and bitcoin was being use for its anonymous transaction. But when the Silk Road was busted by FBI, slowly bitcoins influence subside. But I think, bitcoin is still being use there but as of now, there are many secured coin to be use as an option. We dont know, what coin they are sought after nd being use now.
