i can think of 2 solutions to this problem:
- Use FIAT to buy GPUs, mine coins with them, then use the mined coins to trade on DEX (decentralized exchange) platforms
- Buy crypto with FIAT directly from other people, that you can meet in forums or online announcements, Localbitcoins.com and similar sites
i certainly would not choose to mine. that's far too much outlay and far too much risk in case difficulties go crazy or there's a general crash. maybe 0.1% of crypto users would ever consider that option.
i'm interested to see how p2p develops in china. they apparently have dedicated telegram groups and stuff. the escrow element is something that needs solving for good. localbitcoins is just as prone to being hammered as anything else on the open internet.
the ideal would be a fully legit tether, but inevitably that will be the most regulated and strangled of all.
the ultimate option would be more and more people choosing to forego fiat completely. at that point there's little that can be done. there must be people already who live a good chunk of their lives without ever touching fiat themselves. i hope it continues to grow.
