Yeah man, I've seen it go from 45k rocket to this price. It's insane.. wish I'd bought more at 45k LOL!
Unfortunately, I bought LPC at 11k satoshi, then sold all of my coins at 50k satoshi. 
I wish I would have not sold them too early at very cheap price.
I can imagine.. a friend of mine sold 1 BTC for $750 in january 2017.. 4 months later that same 1 BTC was worth $5000.. I learnt a few lessons from that:
1) never sell your entire holding all at once, but sell in steps
2) only sell at a price that you will not regret later, regardless of how high or low the price goes after that
I admit, sometimes it's hard, but especially in crypto you need to be able to control your emotions
