Id highly recommend checking out robosats, i cant recommend bisq cause i personally have never used it. Setup an offer to sell $50-100 on the platform, something youre comfortable testing with. Get familiar with the process, look at how it secures the funds, even try to see if you can break it somehow. Its pretty fantastic in my opinion, and the only way i buy btc now. They are pushing changes that will make it even more amazing too.
