Cryptocurrencies are an alternative to traditional money. Today, some outlets accept cryptocurrencies as a form of payment. However, they bear little resemblance to other asset classes because they are intangible and extremely volatile. They are mainly used by traders for speculating on rises and falls in value.
You can do a number of things with cryptocurrencies, depending on which one you own. On the most basic level, the definition of a cryptocurrency asset is that it can be used to send value from one person to another or to pay for goods and services.

Binance owns Binance.US’s name and intellectual property. However, Binance.US is managed independently. The main differences between the two relate to financial regulations in the United States. Binance.US cannot legally offer all the same crypto assets that the main Binance exchange can.
While paying for things in cryptocurrencies doesn’t make sense for most people right now, more retailers accepting payments might change that landscape in the future. It’ll likely be much longer before it’ll be a smart financial decision to spend Bitcoin on goods or services, but further institutional adoption could bring about more use-cases for everyday users, and in turn, have an impact on crypto prices. Nothing is guaranteed, but if you buy cryptocurrency as a long-term store of value, the more “real world” uses it has, the more likely demand and value will increase.
