you need to take a decentralized wallet: ex trust wallet in order to have your public key and private key.

There is no need to panic. First, Robinhood is not a scam. It is SEC-registered and even has insurance. Second, you have the option to get out of there. You didn't mention that your Robinhood account is locked or frozen so I assume everything's doing pretty well except that you realized that you cannot truly own Bitcoin there.

So you may get out of there and buy your Bitcoin from somewhere else such as the ones mentioned above this post and then keep them somewhere where you and you alone own and control the private keys. I recommend a hardware wallet. Learn more about Trezor or Ledger.

Since they don't allow withdrawals yet, your only choice is either:

1. Let your current bitcoin just sit on Robinhood(while waiting for them to allow withdrawals) and just start buying "real" bitcoin on exchanges that let you withdraw

2. Just sell every bitcoin you have on Robinhood and use that money to re-buy on exchanges

Ultimately, it's really great that you got interested in having self-custody over your funds. But just a word of warning, you can lose everything if you don't know what you're doing. So before going this recommended path, make sure to educate yourself first.

Since you are frightened, the risks coming may be urgent, wait until the price is fixed, and then you can withdraw your coins from them (if they allow withdrawal) or convert them into dollars and return to the old value.
The price is now volatile and you may lose a few money if you want to withdraw your coins and invest again.

I understand your situation and I know that it is very difficult situation because all these years you thought you have the ownership in your mined bitcoin yet because of the site that you're into, you realize that they won't allow to withdraw. But I think you may do some two way withdrawal. Like, you will cash it in order wallet, online wallets that also teustee and you may now wihthdraw it or exchange it to become a dollar in able to withdraw. I think it has a lot of different ways to fix that and you're the one who have the control to the used email I assume because you sign up for them. Right?

Close your trading position in that website, and send the bitcoin into the other wallets. You can use a hardware wallet, a desktop wallet, or even a mobile wallet so that you can have full control of your funds. When you want to trade, you can send some amount to the exchange, so you can start to trade and make a profit. But you should choose the exchange that will fit you want, and do not try to trade on the new exchange which you do not have more info.

I'm not sure if Robinhood allows users to withdraw cryptocurrencies from their accounts, but you can do it the classic way. Sell all your holdings on Robinhood, transfer them to your bank account, then to an exchange, buy Bitcoin and then transfer them back to your personal wallet - preferably a cold one if you plan to hodl for long-term.

Is there a way you can withdraw your Bitcoin on their site?  If so you can then withdraw it to your own wallet.  There are lots of trusted Bitcoin wallets where you have your own key or passphrase.  You just need a computer or a mobile phone to install them.  Or if you have the money you can use trezor or ledger.  But of course if you are new to this stuff, you can always search the internet to learn to curves of storing your own BTC.

This is the right answer OP. But to what wallet you should use its all depend on you, can buy ledger wallet or use desktop wallet or mobile wallet depends on what you preferred to use that you can own the keys. But first sell all your bitcoin in robin hood and convert it to fiat then  buy from reputable crypto exchange that you can use in your  country .

Once you have bitcoin you should take it the safe place like storing to the bitcoin wallet to more secure the price of the bitcoin is very huge and I think it is not good of what really happen to you. I do not know about robinhood because I did not use it or I've never try it. Try to figure out what is the other way to access or open your account but do not expect about it but try it.
