Bitcoin has a future (unlike the many pumped altques we see lately).
There is a large smallcoin community and will help increase popularity if nothing is devastating.
I'm not sure what will happen when the solved block rate begins to decrease.
Of all I know transactions are confirmed when implemented into new blocks.
If the time between the blocks is too high, people may lose interest because their deals are too long.
But when this scenario will start to have an effect I do not know.
