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?

Same thing applies to me. I personally do want to store up my crypto coins in an open source multi wallet that can cater to hold any typs of cryptocurrencies whether it is Bitcoin or Altcoins specifically those Altcoins that does not belong to the top rank because I have already saw several wallets that cater storing up Bitcoin, Ethereum, Ripple, and Bitcoin cash all together in a single wallet. The reason why I want to store my assets in a single wallet is to of course have an easy access on my assets as well as monitoring their price behavior. Though this storing is risky, I always keep in my that I need to be careful and responsible enough so that no one can access my wallet except me only.
