i will buy more
Me too, I will buy 10 BTC. Even thou btc will still drop into 0.5$, I would literally earn it until bitcoin will rise again. Because bitcoin is so popular these days and there is always a reason why bitcoin will drop into 1$ per Bitcoin.
It will never drop to that price in future, and if it does then before buying we should check the reason behind it and if there is still scope of price rise then we should go for it.
Obviously, there is actually no chance for bitcoin to drop to that amount but if it does then there would surely be a reason behind that and maybe the reason that took it to $1 it may don't let it grow again so that is something we should see before investing into it.
Most of the users will loose faith in bitcoin and will not prefer to invest in, in fact they will quit bitcoin and will switch to some other better product to make investments.
