Your financial freedom with Bitcoin is still guarantee because the exchanges do not or can not have access to your wallet. And the main thing is the wallet. It is when you transfer your coins to the exchange that you will make the transactions.
It's like you are saying you send your Bitcoin to me, and I can't access the funds. If you say that for the self-custodial wallet, I agree. Self-custodial wallets don't have access to your funds. But, when it comes to exchanges. They have access to your funds. They can use your coins to do whatever they want. This is why you see exchanges freeze user accounts and confiscate their funds. There are a lot of cases where exchanges like Binance and Coinbase freeze their user account and their balance. I have mentioned this in many threads so far.
Coinbase Case:
https://bitcointalk.org/index.php?topic=5444423.0 In this thread, OP claims one of his known people had a Coinbase account, and Coinbase froze her account and seized her assets.
Binance Case:
https://bitcointalk.org/index.php?topic=5370726.0 Binance Disabled user withdrawals and asked him to deposit to get unlocked. I would quote myself here;
During the Dogechain upgrade, Binance Mistakenly did some transactions twice a few years ago. It was their developer's mistake. To recover those funds, Binance locked their user's accounts and asked them to deposit to unlock their account. Imagine you withdrew 500K Dogecoin to an unknown wallet address about a year ago.
After a year, Binance sent another 500K Doge to this address, and now they ask you to return that amount. You may don't have access to this wallet anymore. How would you return them? Also, There was a massive pump of Dogecoin. Just imagine your 500K Doge was worth $100 only. But, when Binance asked you for a refund, 500K Doge was worth around USD 80K.
