With an increase of 200%, I would most likely have sold it, because perpetual growth is not possible and obviously there will be a correction, but in generally I would be happy. There were similar cases.
There's no likely or unlikely for me. If it's a coin I hold, I simply don't sell until it is a time I want to, which is still years from now, and many, many times the price it is now, far above ATH. That's not Bitcoin, in case you're wondering.
If it's a stupid coin I know I'm holding to speculate, then 200% burst will simply trigger my sell order for 50%. 25% is for 400% and the rest I hold for fun.
So the decision is out of my hands, that's called disciplined trading, right?
