Here is my answer to how many I own:
I have stopped thinking about BitShares as an investment, and I now think of it more as a path to freedom and an inevitability:
-BitShares saves you from banks that give a crappy interest rate.
-BitShares saves you from central banks that want to steal through inflation.
-BitShares saves you from exchanges that force annoying & intrusive KYC rules on you.
I first heard about BitUSD from Bytemaster's original YT video, and it instantly resonated with me because I was so annoyed at having to send Bitcoin to Bitstamp just to trade it. So I then bought PTS & AGS at that early stage.
And today whenever I hear Bytemaster's philosophical musings about creating value and preventing violence, I get more and more confident that BitShares is going to succeed because it has a moral purpose behind it. So Im still buying more BTS today.
