First of all i want to say that, before Airdrops were had a different idea in my opinion and that is, for example there is a project and they come up with Airdrops of their Token or Tokens definitely it was Marketing tool but for whatever time spent by users they were getting the rewards but now most of the projects coming up with Airdrops but first they are putting line of investment and if they invest this much then gates of Airdrop will be open for them. I may be wrong but in a way it's a way to empower who already empowered. Stay blessed.
