I have the same feeling Bitcoin wont go anywhere if really safe decentralized exchanges can not be developed. This could bring a lot of liquidity to Bitcoin trading. Current situation with centralized exchanges is these can be hacked or inside job can siphon off all deposited Bitcoins, thats why its very risky to trade the Bitcoin at exchanges and this limits Bitcoin liquidity a lot.

The number of possible transactions must go up as well since Bitcoin is almost on allowed transaction limmits decided to be enought many years ago - but technology advances continuously and without more transactions possible Bitcoin cannot be used much more than today, so not dying but on the limit already without possibility to be much more popular option.
