Of course, I do. Who wouldn't be glad seeing his investments increase or double up fast in a year? And now that same thing is not very impossible. Anything can happen like if btc can plunge down that fast within a year, it could do the opposite and we have that evidence in the past weeks.
Surely we all do.Everybody comes into dance mood then, won't they? Also I liked your quote " if BTC can go down so rapidly within a year, it could go opposite in the same way too." And we're seeing some traces like that recently too.
Anything can happen as you said if the price can rise higher it can get down too, because we dont how the move of bitcoin will go this year, so we only need to follow buy low and sell high, when you see market has fallen and price is affordable for you, you should buy more and more because price is gonna certainly be high.
