As of now, you cannot transfer crypto from Coinbase to Robinhood. This is because Robinhood only allows for the buying and selling of crypto, and does not support wallets.
In order to transfer your crypto from Coinbase to Robinhood, you would first need to sell your crypto on Coinbase, and then buy the same amount of crypto on Robinhood.
While this may seem like a hassle, it is actually a good thing. This is because it ensures that you are in control of your own private keys.
By keeping your crypto on Coinbase, you are entrusting them with the responsibility of keeping your private keys safe. If Coinbase were to ever be hacked, or if they were to simply lose your private keys, you would lose all of your crypto.
On the other hand, by keeping your crypto on Robinhood, you are in control of your own private keys. This means that even if Robinhood were to be hacked, or if they were to lose your private keys, you would still be able to access your crypto.
So, while you cannot currently transfer crypto from Coinbase to Robinhood, it is actually in your best interest to keep your crypto on Robinhood. This way, you can be sure that you are always in control of your own private keys.
