Has anyone sold and then watched a coin proceed to moon?

I imagine it's a terrible feeling. There's a couple projects I have that have been stale for a while now and I've been considering reallocating funds, but I'm terrified one of the coins I dump will just take off. Similar events have happened to me before with stocks and that has stuck with me for a while, but that was watching a stock go up like 200%. Nothing like coins doing 1000x. I'm sure many of us feel we have bad luck and whenever we sell then the cosmic powers decide now is the perfect time for the investment to go up. Has anyone actually lived this nightmare before? What coin and how has it affected your strategies afterwards? It's the kind of stuff that wakes me up at night.
