there is no need to worry about the future of bitcoins, I think bitcoin will have a bright future. maybe in the future, the cryptocurrencies will be the new way of payment. now a day, people always panic when the price decrease, but that is a normal thing. I believe in bitcoin and cryptocurrency future.
I think after 2 years bitcoin will dead forever. I don't see good future i am not against it just giving advice. See the low price of bitcoin from last 8 months and make your decision
