If you have a verified Binance account then you can see that the hidden Gem is TKO (for now) at the time of writing this thread.
Maybe the BNB holder to take part in the Subscription has passed because it's now on its 5th day, but you can wait for trading to start from TKO on the Binance market itself.
Usually, for the initial trading of the IEO coin on Binance it will feel like a pump, it can even be more than 100-400%.
