can we deposit waves from bittrex to coinbase?
The answer is no, Coinbase only has LTC, ETH and BTC on the platform. I suggest you download the waves lite client using the Google Chrome browser and pick a secure password. I do not believe that this platform has 2FA authentication just yet.
You could also store your Waves coins at Bittrex, but it is better to hold your waves coin in the Waves wallet. You also have the ability to do leasing of your Waves from the wallet.
Best of luck to you!
