I bought BTC at $20. I sold at $1000. When I sold I had something like 1.95 BTC (had a bit of it stolen from poorly secured exchanges, lost some trying my hand at bot trading). Still happy with it because what I bought at the time with with it made me happy (Sonos speakers and photo gear). Would it have been nice to hold onto it until it was $50k? Maybe. But I have been enjoying the benefits of what I got for far longer.
Having said that, I think XLM is in a good position to jump up in price and I still have their free initial allotment.
