Hello,
which coins and tokens can I store in Metamask?
As of now within the limit of my understanding, Metamask only supports ERC20 Ethereum based coins and nothing more.
I just watched some videos regarding Metamask's developers that they're on their way to add other coin platforms like NEO, NXT and QTUM but I don't think they're published today.
Metamask is limited only for ERC20 coins for now.
