In the earlier guide, I mentioned how you can securely store your Seed Phrases/Private Keys. This will be on how you can use something like Metamask for trading on decentralized exchanges.
You may and will want to use decentralized exchanges for quicker, safer, and anonymous transactions. The main hurdle to start using it is, either you will have to use a centralized exchange first or have someone transfer the crypto for you.
Using a non-KYC compliant centralized exchanges can be the way to go. Some of those Non-KYC compliant exchanges include OkX, Bitget, and KuCoin, even though generally, there is an upper limit on how much you can withdraw without KYC (Know Your Customer). It is not wrong to think for privacy in crypto space as you may not want to associate your name with your crypto wallet.

As with decentralized exchanges, it comes with higher transaction fees or let’s say added network fees. Why? Because they have nothing to do with your ‘Account Label’ or IRM like in a centralized exchange. So, every action carried out comes with a bit higher cost, hence you might not be wanting to use centralized exchanges always as well.
Switching to cost-efficient networks like Polygon, Arbitrum can save you a couple of bucks on the way. Decentralized exchanges are freer from any sort of “Liquidity Crunch” as seen popularly lately on different centralized exchanges out there. Pancake Swap, Uniswap, 1Inch are the popular ones out there to try. DEXs might be missing the margin and leverage feature as well. Margin Trading is always high risk, high profit by default. Overall, I consider DEXs (and non-custodial wallet) to be safer and more secure in every way.
Let me know what you think about DEXs in the comment section below.
