I think Crypto will still exist in about 10 years, who knows? Until now Crypto has always provided good benefits to users, as a payment or investment.
It will exist even longer than 10 years as long as people continue to use and support it. In the future more countries might recognize crypto as currency and it will be added as one of the payment method together with fiat and other existing application that is accepted by people.
Cryptocurrencies are really popular nowadays compared to how it was before. It is one of the reliable investment that many people trust specially now that even there's a pandemic, crypto market is still improving.
