nobody knows who is going to be winning the race and who will dissapear-so diversification like you have is good
since we do not have a long history in these products pure technical analysis wont do either but fundamental stories are important-you will find great principle based tools in my past postings-check them out-personally i like the stories of IOTA,DASH,Ethereum,Stem and litecoin,I also have positions in EOS and Zcoin but those are a bit smaller-bitcoin to me is like what AOL was to the internet I think there's money to be made but it wont survive...there is nothing wrong with your portfolio but i would may be add couple more like IOTA and DASH...
