This sounds like a great plan.
I already purchase SPS on the Crypto.com exchange, and it's been a very handy way of obtaining SPS to transfer into my game without having to use a credit card or to spend other crypto. That said, I'm limited on how often I can transact on Crypto.com due to the limitations of connecting certain bank accounts to Crypto.com.
Listing SPS on Binance and/or Coinbase would be, in my opinion, GAME CHANGING! I conduct the majority of my transactions on Coinbase, and adding SPS to Coinbase would make SPS way more accessible to players like me who frequently use Coinbase. Binance would also be a good choice for the same reason, despite being a little bit less flexible than Coinbase.
Speaking of Binance, I noticed that the proposal did not distinguish between Binance.com (the global exchange) and Binance.US (the United States exchange). Assuming SPS would be listed on Binance, would that mean that SPS would appear on both Binance exchanges? Or would it be limited to either Binance.com or Binance.US? That is something that needs to be considered before going forward with the proposal.
That said, I will vote in favor of the proposal.
