sorry to say but this is just a funny or silly question. 
as the day by day the people r diverting on on line purchase & sell & even the users r getting increase for using mobile phone or smart phones & internet, its a silly question.
for me the Bitcoin's future is excellent. its not easy to delete any currency when its not physical except some miracle happened otherwise Bitcoin will be in use till humans will keep using internet for business &/or playing various on line games or casinos.
i request u to buy & use them then u can understand why its future is excellent. sometimes self experience teaches more than theoretical methods.
so just chill & don't fear. enjoy mining
