i think bitcoin can survive for decades or centuries imo
it still just facing issues now as what i can see

The only way that bitcoin could actually die would be if nobody was willing to operate the mining infrastructure. Bitcoin is not dying, it is only in its baby steps. The reason why people instantly assume that bitcoin may be dying or is dead is because of the extremely volatile price. Since the MtGox crash in 2013 the prices have been on a decline. This is purely due to the numbers coming back to where they are supposed to be.
Its taken 2 years to recover apparently.
And its still going, so I assume when we have a better exchange that helps us out or some other major adoption will help.
