Great suggestions. The diversify and reinvest is sound for the passive investor.
To me, it all comes down to research. If people would research what they are into, they would fare better.
At present, my main token holdings are BTC, ETH, LTC, BTS, STEEM, and another coin that is being introduced shortly. The later three are projects I believe in and follow very closely.
Recently, I took some off the table in both BTC and ETH after nice run ups. I dropped my BTC holding about 1/3 and my ETH 25%. In terms of percentage of portfolio, BTC is no longer my largest holding, it dropped to 3rd and moving towards 4th. Ironically, the run up in other tokens helped to rebalance my portfolio (along with additional capital).
As much of a loudmouth blowhole that he is, one thing that I like which Cramer said, if you cant spend at least an hour a week on each stock you own, you shouldnt own them.
I believe this with coins..if you cant spend an hour a week studying what is going on with each of your holdings, do not own them. Things can change very rapidly.
