They did not announce officialy the lunch of their token so the the number and price is not determined yet but expert analysts are saying that they could lunch their own token and they based their prediction on the fact that a lot of decentralized exchanges lunched their tokens and they gave big airdrops to their supporters after the uniswap success.
Did you see that if UNI and 1nch were not also giving an announcement regarding the launch of airdrop? dydx has possibility to do that same and this time it looks like people are starting to use this exchange site as the daily trade volume is growing more than 100% from a few days ago. it looks like people are also aware about the possibility for dydx to did such airdrop.
I will try to do some trade soon.
