Many of us prefer to hold multiple kind of coins. What do you prefer: holding it in a sigle kind of wallet or have it on a different kind of wallet?
Personally, I prefer to store in an opensource multi wallet that support all my preferred coin and even ERC20 token, its the only opensource multiwallet available called Hodler and so far I find it good. Do you think, this is really good idea?

If you have to choose which coins you should specify for mid-term investments (4-6 months) from the list? I was interested in that choice, perhaps it would be my idea to choose later.
