good post, i liked it.
i totally agree with the main idea of it an actually i was talking about it with someone the other day, that you should always buy when everything is calm and everybody is desperate. that is the time when price is at the lowest (with the exception of weird unexpected stuff like bitfinex hack and the drop).
and if you buy then you can make the biggest profit.
Agreed.I too follow the rule given by Warren Buffet,"Buy when every one is selling and sell when every one is buying".I have followed this and gained more profits.
