Also, this had already happened to TRX at HitBTC. Price for it was way over the top. Almost 100% higher. All the people buying cheap at Binance and willing to sell higher only found out that HitBTC has technical issues with TRX deposits and their TRX got stuck.

After HitBTC solved the issue (it took a day or two), the price went down to level of price at Binance in one 5 minute candle.

If there was no technical problem, there would not be lack of TRX at selling side, and price never got so much over the top.

Same will happen once all the free IGNIS from air drop actually reaches the exchange.
