Are you planning to sell your Bitcoin? If so, then just follow their advice, which is to move it to a DeFi wallet. But I suggest you only transfer a small amount initially, just to test if the transaction goes through successfully. Once you confirm that the process works, that’s the time to transfer your full balance and send it to whichever exchange you prefer for selling your Bitcoins.
No.. I am not planning to sell the coins anytime soon. They are for my retirement fund. But I am quite worried that I may lose access to the coins.
Wow, congratulations! I'm happy to hear that you really HODL. I guess you should follow @OmegaStarScream's advice to buy a hardware wallet, as that's safer than keeping your Bitcoin on an online site, even if it’s non-custodial. You should find an easy process to transfer your DeFi wallet balance to a hardware wallet.
