Really? I've bought many things with bitcoin and now a few with etherum ( although its client software is good awful electron bloat ). I see this line repeated and it just isn't true. Computer parts, everything on overstock, gift cards, vpns, Vps, domain registration, nootropics, etc are all there for multiple cryptocurrencies. People who say this have their head in the sand. If Bitcoin core hadn't destroyed btc, steam, Newegg, tiger direct and dell would all be available.
