I like the idea of cryptocurrency and do hold some. However I also do wonder about the validity of them as in themselves they are only worth what someone is willing to pay for them. Plus unless you are earning in crypto then all you are doing is using fiat to buy crypto to buy goods and services... which you could have just bought with the fiat in the first place.
Yes they are some added benefits like being inflation proof and speed of transactions but they are a long way off from mass adoption
