90% myself, 10% from various groups
give yourself your own judgment, the decisions of others do not guide you
I. Made my portfolio by myself from the coins that I chose from a number of different cryptocurrencies on the basis of their current value, all time high, market demand and several others. I also have seen various threads about the best coins to invest in and many more and also i have told others what my portfolio contains but I have never taken any decision related to investment from anyone else.
