While much of the trust and reputation of both Binance and Binance.US depends on the support and functionality of the two platforms, customer support is not the only factor that may affect their reputation. One such factor is the number of outages that the platforms have had, something far more common in the rest of the world than in the U.S. and a particular issue in mainland Europe. On this basis, Binance.US (despite being the newer platform) has experienced far fewer problems recently, boosting its reputation in territories that can access it.
It's likely SafeMoon - the 203rd-ranked cryptocurrency on CoinMarketCap - will eventually be listed on further exchanges. This is especially likely after Coinbase CEO Brian Armstrong tweeted in June: "Our goal is to list *every* asset where it is legal to do so."

Although few cryptocurrencies other than Bitcoin are widely accepted for merchant payments, increasingly active exchanges allow holders to exchange them for Bitcoin or fiat currencies — providing critical liquidity and flexibility. Since the late 2010s, big business and institutional investors have closely watched what they call the “crypto space” too.
We can speculate on what value cryptocurrency may have for investors in the coming months and years (and many will), but the reality is it’s still a new and speculative investment, without much history on which to base predictions. No matter what a given expert thinks or says, no one really knows. That’s why it’s important to only invest what you’re prepared to lose, and stick to more conventional investments for long-term wealth building.
