Crypto can undoubtedly be the currency of the future. But I think it might take some time for that to happen. The main reason for this is that there are numerous cryptos currently in the market, but not all of them are 100% secure. There is a class of cryptos that most often get scammed or their projects fail. But globally speaking, some coins like Bitcoin can make a special contribution. Also these coins will have more acceptance than all other cryptos.
