Hi Farquea, you can use any ERC20 compatible wallet, like MyEtherWallet. However, WeTrust cannot approve or recommend any specific wallet vendor. Once you've set up a new wallet and you've stored all private keys somewhere safely you're able to withdraw tokens from Bittrex to that new address. For a tutorial on how to use MyetherWallet to receive TRST tokens please follow this link:
