I completely agree that crypto will be the currency of the future. Cryptocurrencies are already used all over the world and constantly more and more countries begin to legalize cryptocurrencies and recognize them as official currencies, this is just a matter of time when the whole world will already fully begin to use cryptocurrencies with its full potential.
If you say the future? it looks like fifty-fifty, in terms of the concepts that exist in cryptocurrency is a concept that is needed in the future, where transactions are easy to use. Can make transactions anywhere and outside the country easily, digital concepts are also things that are needed in the future. Moreover, cryptocurrency has technology that promotes data transparency and data security.
Why do I say fifty-fifty because cryptocurrency still has weaknesses. Examples of bitcoin and some other coins that have high prices will find it difficult to make small transactions. Whereas the stablecoin that is said to be suitable for a transaction does not yet have a way to make a purchase transaction directly.
