After TON Wallet became available in the US, I started using it actively myself due to the need for very fast transactions, primarily driven by the gold rush of Telegram gifts.
And I can say that with the Omniston protocol, also recently integrated into this wallet, trading there is no different from trading on any major exchange. Yes, the interface is simpler than on exchanges, but is that a downside?
While exchanges like STONfi offer more precise trading tools, for the need to quickly exchange tokens for $TON, for example, to get some gifts, TON Wallet is an excellent solution to react quickly.
And looking in another direction, US availability will allow a huge number of traders living there to trade, which can influence $TON and increase its popularity, as there are quite a few traders there.
