The bitshares merger is overwhelmingly approved by users and delegates. When was the last time Bitcoin development direction were put up for a vote by all users? was the blocksize hardfork put up for a vote by all Bitcoin users?
do you think the Bitcoin cap can't be raised if there's a need for it and users overwhelmingly approve? How is this even related to PoW vs PoS at all? in both system, the cap CAN be raised period
One man's trash is another man's treasure, I sold my stake of Bitshares every time there's a rule change (PoW to PoS, invention of PTS/AGS, proposed merge /dilution), which reflect the trust and confidence I have in the system.
I am not predicting the failure of Bitshares, I just don't feel like playing a game that rules constantly change.
Edit: Selling stake in Bitshares included its predecessor PTS. 3i created AGS (and subsequent BTSX) because they lost the competition in PTS mining.
