3-4 times of return is already a great sale. We're in it to profit on this market but we just have different goals and that's why others are encouraging to hold more and they're giving a good suggestion.
And that's about selling when you have to and if you have nothing to spend it for then just leave your BTCs alone and plan something until you decide to sell.
It will take a while until we see some great price again for BTC because this is once in a life time opportunity and people who have sold might have hard time in buying one again for themselves.
Since bitcoin prices are always fluctuating - then believe me, we will all have the opportunity to buy low and sell high. Someone who sold at $123K could buy back at $117K - they make a profit, while accumulating more bitcoin. It depends on how much return each individual expects - but if it were me, as long as I still don't want to sell then I would keep holding.
Of course, earning 3-4 times the return is great for an investor - but only a few actually achieve it. I haven't earned that much from Bitcoin myself - and you probably haven't either, unless you bought it way before me and never sold it at all.
