Some people never really be bothered to use BTC but instead just want to take some profit from the bullrun, it's like when some people buy stocks do they care about the company condition? some of them do but there's also many who just don't care and just want profit.
It's the same case here, imaginary btc but you can get real profit by bagholding, not really a good practice but in their business perspective it works just well considering the trading volume.
