Here is what I hope happens. I hope all the big world banks panic and start offering ridiculous amounts of cash to pick up all the big central exchanges... right around the time we figure out how to get usable decentralized exchanges with high liquidity. Late to the game again.
We can't figure out a way to decentralize exchanges with FIAT involved. if you have high trading volume, they will find you. Polo is not getting out with your coins, some people think that, they are scamming, they are giving up. they will all give up.
We have a few threads on Bitcointalk, they are acting as usable decentralized exchanges, why do you think that people are competing for being the most trusted escrow?
That is good for all who don't like polo and hope future of the existing will be better than polo with high volumes etc.
Everybody likes Polo, they always had the highest trading volume, they just couldn't resist the temptation.
