Depending on the chosen strategy, the ways of storing cryptocurrency also differ. Cold wallets are better suited for investments. Thus, you can keep the cryptocurrency on a computer or flash drive. Exchanges are best for trading digital assets. On them, the client can sell or buy cryptocurrency at any time, as well as take advantage of additional options. For example, leverage, which can be used to manage additional capital.

As a result, the bettor receives money or loses it.
