Binance explains why Monero doesn’t “meet their high level of standard”.

At Binance, we periodically review each digital asset we list to ensure that it continues to meet the high level of standard we expect. When a coin or token no longer meets this standard, or the industry changes, we conduct a more in-depth review and potentially delist it. We believe this best protects all our users.

When we conduct these reviews, we consider a variety of factors. Here are some that drive whether we decide to delist a digital asset:

• Commitment of team to project

• Level and quality of development activity

• Trading volume and liquidity

• Stability and safety of network from attacks

• Network / smart contract stability

• Level of public communication

• Responsiveness to our periodic due diligence requests

• Evidence of unethical/fraudulent conduct or negligence

• Contribution to a healthy and sustainable crypto ecosystem

Especially I like the "Responsiveness to our periodic due diligence requests". LOL. What do you expect, it's not a company driven project like all the others. There is no one to respond. That's a feature, not a bug.
