Using a hardware wallet such as Ledger or Trezor is a fantastic and safe way to store your tokens.
Please use the setup guide for your Ledger here https://kb.myetherwallet.com/migration/moving-from-private-key-to-ledger-hardware-wallet.html
Using a Ledger is super easy, just install the Ledger Live program on your pc, let your Ledger firmware update, install the Ethereum app and copy the wallet address from Ledger Live so you can paste it in the withdraw window in your exchange.
Also install the MyCrypto program from https://download.mycrypto.com/so you can manage your ERC 20 and 223 tokens because Ledger Live currently does not support them. MyCrypto is a front end wallet interface, same as MyEtherWallet and using the MyCrypto program ensures you can't get phished.
Do a small DGTX test transaction from your exchange and after it has been received, send some back to the exchange by using the MyCrypto interface.
When you try to open up your Ledger DGTX wallet though MyCrypto, please select from the dropdown wallet addresses list that has the (m/44' /60’ /0’ /0) code and then your wallet will be first on the list below.
Doing the withdraw test will ensure you know how it works and have faith in your storage. After that you can withdraw your stack and forget about it for a couple years.
DGTX Wallet information and recommendations
Hardware wallets such as Ledger and Trezor are the best and offer the highest security but cost around $70–$150.
Software wallets like Enjin, Trust and ImToken are great free alternatives but with the Private Key being on your smartphone, they come in second place to the hardware wallets.
Browser extensions like MetaMask are okay but not recommended. Also MEW is most commonly compromised by phishing attacks so please consider not using it at all.
As always, have a backup of your private key or seed words. If you lose your crypto wallet and don't have the backup somewhere safe, you lose all your tokens.
