@crypto.piotr, Airdrops are really effective and in this point there is no doubt but the first question arises, Airdrops are empowering people or restricting them?
In my opinion nowadays Airdrops are restricting people who are not able to invest anything. But initially when Cryptocurrency brought into the picture and establishment idea was different but now we are moving away from it.
It's time to bring the true idea of Airdrops and with that projects which have real use case so that people will feel to invest their time in it, otherwise we are spreading the mess in Cryptocurrency Economy and then Scammy Projects can take advantages of this mess.
And participating individuals should also gain the knowledge because in this way they can measure their investment ideas and they can better analyse the use case of particular project.
Stay Blessed.
