I saw the point of crypto and Bitcoin in 2013 but I wasn't too into it at first because I could see that it potentially wastes a lot of Energy. Only at the end of 2013 I started to look into it deeply. Then I discovered SolarCoin in 2014 and the rest is history. Now into SolarCoin, ElectriCChain, Ethereum, IOTA, Steem and many others. It is probably the best invention in the last 600 years.
