re: OT: anyone doing any investing in Cryptocurrency?

IOTA is supposed to be the next big crypto, from what I've read. They are apparently going away from the "blockchain" methodology and using something else (I think they call it tangle)....but it eliminates the "mining" that is done with Bitcoin, which is a major drain on the power grid. Apparently Microsoft and Samsung have both jumped on board in some capacity with either backing or using IOTA.
