Bitcoin is readily available for now and there are different ways to buy it, which the Op mentioned above. But the problem is the privacy factor.
- Anyone who cares less about their privacy can buy bitcoin in any reputable CEX.
- But if we care much about our privacy, we need to sacrifice more to be private. We need to be somewhat tech savvy to be able to use DEXs etc.
But generally, CEXs are the most popular place to buy bitcoin and they are the first contact of newbies in the industry. Some newbies who try the DEX could get scammed if they don't know how things work there.
Using modern DEXs is not that hard. For example, we can easily use platforms like Bisq and other DEXs for various coins (excluding BTC), such as PancakeSwap and Uniswap. Buying isn't difficult while maintaining privacy, but acquiring USDT can be a bit challenging. To remain anonymous, you often have to outsource acquiring USDT through other people, and at that point, it becomes difficult to obtain it without providing some personal information. I can’t think of many other ways to get USDT while maintaining privacy in my region, given the resources available to me.
I'm not sure how people in other parts of the world are buying USDT to get BTC or how they're managing to buy BTC directly, even via P2P, while maintaining privacy. Although you don't have to be tech-savvy, I agree to some extent that you need more knowledge, like understanding wallets, especially non-custodial ones, knowing the difference between DEXs and CEXs, how to sign a transaction, and which transactions not to sign. There's certainly more to learn with DEXs compared to CEXs.
