Psy have two mining contracts with https://www.genesis-mining.com/
1 for Ethereum
1 for Dash


These were both purchased with 1 coin of each blockchain..

2 years ETH contract cost 1 ETH (at the time that was 50$)
2 years DASH contract cost 1 DASH (at the time that was also 50$)

Both DASH and ETH surpassed the 1000$ mark and then some.. Had Psy held these coins rather than trade them for contracts Psy would have done better.

Not sure I'm into mining. If it was limited to CPU.. yes, but it is a rich mans game now.. Staking is the future.

EOS has 21 delegates, Lisk has 101 - Sure this is more centralized on a "central to distributed' scale than any Proof of Work coin... but we can also change our votes...
