You should definitely add some btc and eth. At least most known and establised Blockchain-Tech.
Also have alook at waves plattform, they will do great in 2018 when business starts to get into blockchain
These are some must-to-hold coins in any portfolio. Some may think they have reached their peak now and too expensive to buy, but as far as I am concerned, they are coins that would keep surpassing people's expectation and they are well established already compared to some other alts that could collapse anytime due to their limited support.
I really do not know much about bitbean but I know deeponion is a good one to add to your portfolio as that is some good coin that you can hold and expect that it would come out well for you in the future. Your portfolio totally depends on you though and it is always good to do your research first before investing in any coin, and as long as you can get this done, you would not have a problem.
