BTC will rise. I think you should hold a major portion and carefully trade altcoins with the rest.
If this guy is the type that panics a lot, then he might have sold his Bitcoin, possibly around the time price dropped to $6000. And if he did, I know that he will be regretting it by now. But if he didnt, he will be very happy cause price is at the $7500 rate as of when he posted this, but $10,000 now.. Its always good to have patience, cause volatility is a normal thing in every market, price fluctuates some times; might fall below the original price or go above that.
