I have a question, when i buy MTH on binance, where wallet can I hold MTH for long term. I don't want place it on binance
Since MTH is an ERC20 Token based on the Ethereum Blockchain, you can just create a wallet at myetherwallet.com and transfer it to this wallet. Be sure to store you're private key on a very safe place! (Which is preferably not your computer but a piece of paper)
