My thought is that these projects can just state it from the early stage that they will be demanding from their participants to pay some TON fee at towards the end of the entire tapping and task fulfilments, and not to take people by surprise when they never expected it that way.
They won't do that. Why? because the participants will lose their appetite to keep on grinding with the projects or apps that they make. If they will announce it too early, only a few serious one are going to be left and those that are willing to spend bucks with these projects but the majority of them will just leave them hanging.
Let's just say airdrops are free nothing you have to pay if there is something like this you can skip it sometimes this is a condition for eligibility on the other hand we think they are scamming us by sending a little TON so here you can do some research on the airdrop.
I know some airdrops on telegram now have to have a little capital outlay, because some other airdrops follow the same way as the previous airdrop.
Make sure you can see their social X.
See how big the community is.
Whether the team is known or anonymous.
But all of this doesn't guarantee that the airdrop is legitimate because it can't be confirmed yet.
The last part is what every airdrop person needs to learn about. Not all airdrops are going to guarantee money even if they will pay TON for the fees that are being asked by the project. It may go south afterwards and many will be disappointed by the outcome of it. So with this, take it as if it's also a gamble when you're willing to spend these amounts but even you'd do it for free, you're also spending your time on it even if there is no assurance that these projects are going to be successful once they're on the market or once they have concluded the airdrop period is done.
