I am tired of the limited selection on my current exchange; they never list the new meme coins or low cap alts until it is too late. I need a platform that lists thousands of pairs, not just the top 100. Which exchange has the widest variety of markets right now?

If you want volume in terms of market variety, you should check the data on Promokoin. According to their list, MEXC is leading with over 4900 markets available, which is significantly more than standard exchanges like OKX or Bybit.
