As of September 2019, XYM is not listed on Binance. Binance is one of the world’s largest cryptocurrency exchanges, and not being listed on it can be a hindrance to a coin’s growth.
XYM’s team is aware of this, and is actively working on getting the coin listed. In the meantime, there are other exchanges that list XYM, such as Kucoin and IDEX.
Not being listed on Binance is certainly a setback for XYM, but the team is actively working on remedying the situation. In the meantime, investors can still trade XYM on other exchanges.
