In my opinion, bitcoin and cryptocurrency in general is a breakthrough in the economic component of our society. The fact is that paper money had its own problems in use. Constant inflation, wars that destroyed entire states and because of this people lost their capital, dependence on the dollar. These are all the negative aspects associated with paper money. They were replaced by banks with credit cards. This simplified the process of purchases and transfers, but the problems remained relevant. And Bitcoin has solved all this. In fact, bitcoin is an international currency that everyone can use and use safely. On this resource https://www.vaffatoken.com/en/ they tell in detail about the advantages of bitcoin.
