Just trade on the popular and good exchange. Before starting trading make time to search and get feedback on this exchange. As we all know there are many issues like hacking on a certain exchange so be careful and choose a good exchange.
Exchange with less volume is not popular and they aren't because they have poor marketing and maybe weak security, that's why people prefer a big exchange like Binance. The question is, if we are trading on a regular basis, what we really need? of course we need liquidity so we can trade all the time and we can see that liquity in big exchange, therefore we should focus trading in big exchange.
Small exchange is good if we like to experiment or maybe buy some shit coins that we think a hidden gem as it's not available in reputable exchange.
