today Cryptocurrencies are at the level of a concept that can evolve into something more. Investors expect that the cryptocurrencies will become something great, as in their time social networks, and then with the increase in the user base, the value of the asset will also increase. But what should happen to make this applicable? It should be simple and convenient. For example, Telegram is simple and convenient. And there is a Signal messenger - superanonymous, but not so convenient. Therefore, it uses far fewer people. Humans are creatures in a good sense of being lazy. They do not need unfinished products. No one will delve into private keys, backups and the like. So far, to explain what cryptocurrencies are, it takes 15 minutes - most of this will seem nonsense.
