Hey there, my friend. I can certainly understand the frustration of losing access to your BTC due to lock down periods on various exchanges. It's unfortunate that these centralized platforms can often be unreliable and prioritize their own interests over those of their users.

I believe that a truly decentralized exchange exclusively for BTC is an excellent idea, as it would provide the security and privacy that many in our community are seeking while also eliminating the need for KYC processes which can be invasive and time-consuming.

As for privacy-oriented solutions like CoinJoin, I think they have great potential to help protect user privacy while still maintaining the transparency and security of the Bitcoin network. However, it's important for individuals to take responsibility for their own financial sovereignty by educating themselves on best practices when it comes to using these tools.

Overall, I appreciate your input on this issue and hope that together we can continue working towards a more decentralized future where financial freedom is accessible to all.
