I am affred what i will do if it will happen
If you are not sure about the future of bitcoin then don't buy it. Just spend some more time on this forum and read some more information about cryptocurrencies. Then in some weeks you will learn to analyze and make your own opinion about cryptocurrencies.
But generally witcoin would worth zero only in case if all miners would turn off their equipment. If that won't happen then BTC won't fall less than 1$.
I agree op make crazy thoughts about bitcoin haha. Well actually a lot of discussion people asking what of bitcoin goes into zero value. That people make thread against the bitcoin to blame people to stop investing in crypto, a lot of the people asking same from the op is not well known the importance of bitcoin.
