We see in this mounths that many dex exchanges like uniswap badger and 1inch lunch their own tokens and give a massiv airdrop to all the connected adresses
Founder of dydx said in an interview that the platform will lunch a token maybe in the beggening of the new year and i advice everyone to connect their wallet before its too late
It looks like the trend has changed now, that is, if you trade in some Dex exchanges you will be qualified to get their airdrop like in the case of UNI and 1Inch, actually it is a good idea at least to reward users who believes in the exchange. However, it would be wise to be careful and gets the facts right henceforth with other forthcoming exchange airdrops because scammers don't joke with opportunities like this to create theirs and make their money. Also, with the number of exchanges which will come up just to do this, one will only but pause and ponder how their long term sustainability will be.
Nevertheless, there is no harm in trying, since the founder said so in an interview, maybe it's worth giving it a shot.
