Hm no, uTrade is not just the best choice for ONT users, it is also the best choice for WING users.
Because, as more trades happen on WING/ONTd on uTrade, more profit goes to people who lock their WING on uTrade. Thus increasing buy demand for WING.
On the other hand if you do a trading competition on Binance, you increase trading volume for the duration of the competition, then it quickly returns back to the normal afterwards. Traders get in, then get out, buy demand is cancelled out by sell demand, and the price may or may not move up or down. The biggest upside is marketing from Binance, a temporary volume spike, and eyeballs from traders, but to them it’s just tickers on a screen. Very unlikely they will withdraw WING and use the platform, which is the goal for sustainable long-term growth.
I’ve been a part of Binance trading competitions before for other tokens. The one who really profits is Binance.
