So, I currently have a shit ton of TRST on Bittrex at the moment, and it's making me very nervous. What wallet should I use to store these coins offsite? Also have some ETH so would like to store that too in the same wallet, if possible. Thanks!
Myetherwallet is good, especially if you use it with a Ledger Wallet Nano S. You can use it for Ethereum, Bitcoin and Ethereum based tokens.
That is what I use... It works a treat.
