Crypto has vast number of applications other than trading but there are few countries which actually implement crypto for buying goods and services. But can you imagine how crypto currency can be beneficial for company, companies can use it as monthly wages if employees allow it. But right now Crypto is just seen as an asset which is traded on exchanges and converted into fiat but in future we will see many uses of crypto
If many country starting to accept crypto then possible it can used anything like used as payment in store or give as salary of employees, but since it only used as trading and it only become fiat when someone exhanges it to their currency. And I think cryptocurrency is now can used as payment in some site and accept in some country, maybe when years goes by crypto will be used not only as asset but lot of uses.
Right now some country is planning to accept it and some country is starting to accept crypto like in Japan. I heard that in Japan they used crypto as a wages for their employees. So I think cryptocurrency not only for trading and asset but only as payment in the future, we all need to do is still wait for it to happen and wait for our country to accept it.
