1) ....you must apply the techniques of the big investors, which is "Wait as long as necessary, until you get a gain ".

3) Volatility can do everything faster, but the key is knowing how to wait, in fact, now is a good time for investment, I have as a premise that the value of Bitcoin of less than $ 10k is always a good price.
1) I don't know where you heard this from, but that's not how (big) investors do their thing. They're on constant watch to the Market price charts, and every time they see profits they will not hesitate to trade, rinse and repeat. Holding is not really an investors strategy, but a Hoarder.
2) I can sympathize with this. You could use Volatility to your advantage if you know what you're doing.
3) Though we could argue that statical-prediction does not really portray the actual result, but we can at least expect something, rather than going in blind.
