For countries like Venezuela and Argentina, Binance has a messianic reputation in the sense that P2P currency exchanges are what keeps the economy functioning for the lower-rank citizens. Top-tier citizens just use Zelle, but as you might not know, not everyone can afford/is allowed to go the U.S. and open a bank account (e.g. I, for instance, was denied a tourist visa last time, though I am more than able to afford vacations there).
If Binance were to fail, other P2P exchanges (like Reserve, Airtm and the now-dead Localbitcoins) wouldn't be able to take up with the current volume of P2P transactions of both countries.
I'm not saying these countries would grind to a halt as "direct" P2P currency exchange would still exist, but people that rely on Binance P2P for their day-to-day operations would downgrade their lifestyle, big time.
