If there is one thing I've learned above all else in this market, it's that if you are feeling euphoric and hopeful, it's time to sell.
I do not see this being any different. As a matter of fact, I sold 50% of the alts I have back into BTC for this very reason. I made substantial profit these past few days. Normally speaking, I'd let 'er ride. Not this time.
Stay safe out there people. Remember, these whales will paint the charts however they want to get you to FOMO in.
