After this rally up that might get the price of BTC up to 1,300 usd, I am pretty sure BTC is going to crash again and it will hit the 400 usd.
What do you think?
Crash is really possible but not to the point it will go back again at $400. Yes it has chance but today's bitcoin is different from the status of bitcoin in the past where coins today are much distibuted in different exchanges. So if a crash happen in one exchange, the downfall is not that much.
I see correction price closely to $1000. If it's go back to below $400 then that is really a doom as it proven that bitcoin can't maintain it's support from the community even with lots of users today.
I agree with you when you say the today status is different from the 2014 status. The situation is different now, since 2014 many more persons started buying bitcoins and many more bitcoins were mined. We know the price won't steady in the price we see now, but I don't think the price will regress to 400$, it's too low, bitcoin community is strong now and won't let this happen.
