its not about trading on exchanges, but like the example i gave before about Gods Unchained game, if i want buy a card that cost 0.000001 eth , i pay gas around 0.025 eth ... not doable ..
but we will see where this will end , the noices about eth2.0 will bring a solution for this , but then when will this come ? since 2018 / 19 i am waiting for it ...
And that simply is the problem ETH has to overcome first. To make it so that people do not spend more than the thing they actually want to buy or the smart contract they want to execute,,, which is ridiculous by any means.
But fixing that problem they have sacrificed stability,,, let us see how ETH 2.0 fares in an attack first and if that will determine how many people remain on the chain.
