1. Digital currencies are used in commercial transactions for the speed of transfer and ease of use. Recently, these currencies have been used in illegal transactions, as well as by countries that have sanctions, and in illegal trade. This is because most of these currencies are decentralized and are not subject to regulation, although some can be tracked, which makes countries and governments more hesitant to legalize such currencies. This, in turn, complicates matters in determining the future of these currencies.
