As with alot of new crypto coins jumping on to the bandwagon, most are in there pre-release phase that consist of tokens, mainly ERC20 value tokens, and with the ever increasing amounts of wallets and cold storage wallets on the market, what would be the best wallet to use for both tokens and valid altcoins, as I certainly don't need a wallet for every altcoin, is there a wallet out there that supports ERC20 token as well as altcoins. That would reduce this baggage?
I think
coinomi fits your needs its an app with lots of altcoins and its supports erc20 tokens. You can trade their too, they are using shapeshift and changelly in their app. But if you are looking for storage of erc20 tokens only I think the second best next to hardware wallet is
metamask.
