So what's the best coin to buy a cup of Coffee with? Transaction cost must not be expensive and the transaction must complete before the Coffee gets cold...
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,
I will choose Doge to sell the coffee.
Now we can talk about others blockchain because of transaction speed. I'm sure dogecoin or Tron both could be slower than now if we all users start only both of this chain.
