haha very interesting, maybe if I become a coffee seller,
I will accept crypto currency instead of Ethereum and Bitcoin, because you know that fees are high,
Isn't Ethereum and Bitcoin cryptocurrency? I wonder why you exclueded this two from crypto.
I will choose Doge to sell the coffee.
There are lots of cryptocurrencies that are very fast in terms of confirmation and has very cheap transaction fee aside from Doge. Like for instance, there is XRP, Tron, Nem, Waves etc, OP can just pick what he prefer to use.
