As far as I've read and heard, the hard fork doesn't really mean bitcoin will go back to zero.
Yes, hard fork simply means that there will be a snapshot taken and then from that point onwards, two ledgers will be kept, separate from one another.
I don't think they would allow it especially investors.
Uh, what? I agree that bitcoin won't go to zero. But there is no central bank behind bitocin that will rescue its price if it were to go down.
But I don't think long term holders should be scared of what's coming. I myself am a holder of bitcoin and would still HODL my bitcoins and just leave it there for the next 2 years or so.
Agreed, Ethereum's hard fork was originally thought to be the end of ethereum becasue ETC was essentially catching up with the actual ETH very quickly. But now, there is a decisive winner(the actual ETH). As i said, bitcoin will probably experience something similar, it is likely that two chains will be running simultaneously for a while, but towards the end one chain will succeed whilst the community interest for the other one dies off and eventually nobody uses it.
