I think it will lead to a healthier market with less pumps and dumps. Most serious buyers of Bitcoin in the US are using either Coinbase, Kraken or Bitstamp. No one in his right mind loads up on Tether and sends it to Binance. Their USDC vs BTC volume hovers around $10 million (give or take) which is a much closer reflection of the interest in Binance from US users.
But yeah, this might also function as extra stimulator for people to look into the peer to peer market, because when an exchange does what you want it to do, there is no reason to look for an alternative. They have that reason now.
