Before you begin spending your BTC, keep in mind a few things:
- Bitcoin is NOT anonymous; if you buy from an exchange and being spending, it can be traced effortlessly
- Mixers and tumblers only provide obfuscation and can often be useless as you could be trading your coins for dirty crypto

Convert your BTC to XMR (Monero) using an atomic swap. You can find a swap provider on unstoppableswap.net. This prevents fees that may incur from a regular exchange or swapping service.

Non-KYC swapping services:
- OPTIONAL: Consider using Wasabi Wallet (wasabiwallet.io) as your BTC wallet, as it provides an implementation of CoinJoin, allowing you to cover your tracks when spending Bitcoin.
