1/ Math. Math is hard for the goverrnment because they fuck up everything they touch and we all know and agree on that. Math makes too much sense and is incorruptable.
Unlike gov't - key word corrupt.
2 / It has no borders.
3/ It is better than any money or metals and yes, I have metals.
4 / It has more portable, storable, transferable options globally than metals, tied to point above.
I could go on, it is late for me, that should get you started.
If you were not in Steemit, I could not quickly UV a comment and transfer money to you, like this with my vote.
Well, I guess that is my last reason after all.
But I'm looking for a currency cryptos are good I love steem but we still have to fix what we use to barter if everyone made there money by up voting comments who would grow the food make the clothes? How do we distribute this currency?
