It's just another one if those small storms Bitcoin must face. It's faced many and survived and will face many more and still survive.
If a hardfork happens that can split the price into half as well. I personally would not take that chance.
Yes this is true and most of people are thinking the same thing. You can see it in the market right now that huge sell off is happening and even altcoins are down by more than 10% in the last 24 hours and it keeps sliding. They are now saying if it failed then bitcoin will surely be replaced.
