To trade SHIB, if you are patient and can use limit orders I like Webull the best of course because it shows the real time profit and loss in an easy to read way, just like how they do on any futures platform. The fees are very low, barely notice them at all, the spread isn't that big. The next best exchange I like is through the Voyager app. It displays profit and loss the same, however the spread is a little bigger, so as long as you buy deeps dips with limit orders you will be fine. Third best is just trading by swap on apeswap.finance on the binance smart chain because the fees are in BNB smart chain, and are so low. Hope this helps.
