LOL if only the people mining ETH in 2015 is able to see this quarell..you can mine it all in a day with a few 280x hehe
ETH was extremely profitable to mine (in terms of ETH not USD or actual profit) back in late 2015. It had a good launch and then I think those that bought the ICO ended up dumping everything and at the end of the year I think ETH traded at less than $1.
An R9 280X didn't have any DAG issues with a low epoch, it actually mined at 27-28MH/s however it ate 200 Watts of power. So with $0.10 power, you were mining at a loss but generated 1 ETH per day per 280X.
Imagine mining ETH with a single 280X back in late 2015, to sell at $1400 in Jan 2018? Basically what Satoshi felt pretty much. However most like me either didn't mine at a loss or they mined and sold when ETH hit $10 or $20.
To mine at $1 a coin and sell at $1000 is extremely rare.
Imagine being part of the ethereum "team" and getting the majority of premined ethereum with very little work. Many of those team members did next to nothing and got huge bags of ethereum for it.
