I am currently holding some of the big leagues in Crypto like bitcoin, ethereum, litecoin and OMG. I really don't want to invest in many coins it is giving me headaches, you know you are only one person and we have limitations in managing many crypto assets. UNLESS there are good tips on how to manage them all trading, and all.
I totally agree with you that the headache can be real. If that works out fine for you then good. However most of my returns are best from investing in good ico and then converting the return on btc. I still believe that BTC is the king of all crypto and might end the year close to 100K no one knows
