If you would get $10 000 to invest into Cryptocoins, at which price you would be ready to buy?
p.s. good news is that even if you buy at a higher price than you feel comfortable with, you can be fairly certain that bitcoin will rise to that price again in the long term.
Thi is the main reason why you shouldn't care all that much about bitcoin's price. It's true that there is no one who can guarantee that price will be higher in the future.
Yet when we base our judgement upon the history of bitcoin price shifts the pattern is pretty easy to spot, it is never ending upward trend.
Price growth is only stopped (and resumed in no time) by catastrophic events such as a collapse of main bitcoin exchanges (MtGox fail and most recently bitfinex hack and Chinese government intervention) or FUD about potential bitcoin ban.
