You have made a very good point. The value of crypto currencies are unstable and very violatile. As a result, a person might very little amount as due to the price of the crypto involvedI don't think so because cryptocurrency is very volatile and these will make a lot of people to not even venture into it at all because they can lose part of their salaries if they are paid in cryptocurrency. I think it will be by choice because some stablecoins can actually keep your money intact for some period of time.
