Your post made me laugh. Are you serious about what you mentioned above?
Lol i mean it's never a perfect time to buy bitcoin. People always think that when it's down they should buy it. But there they make mistakes and faces losses.
Moreover the price of Bitcoin do fluctuates. So if you have enough money to invest in Bitcoin then do right now and leave the coin undisturbed for a while.
You gonna definitely make profit, i am damn sure.
If one can study the market very well, make use of analysis, then the buy time would not be difficult, the only think I do advise people is not to try this when the market has fully recovered, because it would be risky to do that, because of the market dumping.
