I once heard Alex Gladstein mention that there seems to be a high demand of stablecoins from the poor and unbanked. Historically, btc has always gone up if you can wait a couple of years. But if you can't, if you need money for food tomorrow, you will accept USD's slow decline of 10% per year rather than the chance thst bitcoin can drop by 30% in a day. Being able to survive with only an asset that is as volitile as bitcoin is a privlege of not being very poor. But i see stablecoins as temporary, until bitcoin becomes less volitile.
