That is all the coins I got from the bounty of the companies ( if they have a standard ERC20 ), I can safely send to your Ledger Nano s ? Just I already ordered and want to totally abandon the MEW.
Most of the bounty rewards are made through ETH's smart contract and results as an ERC20 token. Do you mean your nano ledger s? Yes you can safely send it there and keep it for your safety as for this guideline says,
Most of the other Ethereum tokens (ERC20 tokens) can be managed using Ledger Nano S and Ledger Blue with MyEtherWallet only (it won't work with the Ledger Wallet application).
MEW is fine but if you have decided of jumping to nano ledger s, then that's better for safe keeping.
