Good luck to you on your crypto investments.

I too am very interested in keeping large sums on the blockchain instead of fiat or banks.  The world is changing and the little guy is getting screwed.  All central banks have pushed interest rates to zero to make people spend more money and encourage consumption / growth in the economy.  This has destroyed people's savings and destroyed capitalism in Europe and North America.  Now the central banks are interested in NEGATIVE interest rates because raising interest rates  now would drive national budgets into bankruptcy.  Negative interest rates are stealth taxes by central banks that national governments don't have the guts to  implement themselves.  In order for central banks to start doing negative interest rates, first they have to destroy cash as an alternate safe haven for the little guys to place their savings.  This is why all the large denomination bills in all countries are under attack.  In the US there are serious proposals to get rid of the $100 and $50 bills.  I believe this would have happened in the first year of a Clinton presidency and why I am THRILLED that Trump won - even if he is crazy.
