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 want to hold multiple altcoins so you can do it very easily. If you want to put your altcoin in a different wallet so you can do it but if you have some money so you can buy a hardware wallet then you can put your all token in one device. I'm using a hardware wallet to hold my altcoin. I suggest you can put your altcoin in the different wallet because if your wallet hack but you can lose your so token.
