Bitcoins is now climbing its height at its speed. No one can say that it will disappear or become unused at this moment because we know that bitcoins will last long and if something happens in the world all the bitcoins users will fight for that and get the rights what all the bitcoins users wants. Its the power of bitcoins.
Yes bitcoins are going at very fast rate and now it become an integral part of daily routine for many people.
Many people used it daily for their routine transactions. As it is growing fast there is very rare chance of disappearing Bitcoins and I personally believe that it won't happen. Price maybe low or high but Bitcoins always survive.
It is not really going at a fast rate new. The price is just dropping which is kind of scary to see.
