That’s not how it works. ASIC companies like Bitmain, Innosilicon, etc (chinese mostly) are known for immoral practices but they can get away with it given the wild west that China is in general, and the wild west the crypto is in general. They DO mine with them before either announcing them or putting them up for sale – this has been shown time and time again (see Monero, and others, including Grin itself showing a massive drop at fork time). You then get sales, you pay, and then you incur delays while they are still mining until close to the tipping point of profitability vs risk of losing customers (like the OP) when they decide to actually ship out.
That’s the ASIC mining world for the average Joe. The only ones who make profits from ASICs are the ASIC manufacturers and their friends … and maybe the illegal miners mining on 0 electricity (still happens in China and elsewhere).
While ASIC mining is in theory a good idea, in practice it’s been and continues to be a massive failure which is hurting the ecosystem and coins who promote asic mining (even for the right theoretical reasons) only end up perpetuating and exacerbating the problems: bad actors, ripoffs, centralization (you know, that core reason for crypto). Grin is no exception I’m afraid.
p.s. No offense to Grin devs, but the decision for 90%/10% gpu/asic at first to become 0/100% in a few years was not really taken by the community but by a small group of folks, executive style. Fine by me, but let’s not call Grin a community run coin or a decentralized coin, it really isn’t (it relies on 3-4 individuals, if that, some who rely on donations to work full time on Grin). The MW tech is nice, don’t confuse Grin with MW though.
