I've always known airdrops to be free giveaways, but not in this case anymore and the two pictures below speak enough volumes already. This nonsense is no more worth it.
Not all airdrops are actually free there are some retroactive airdrops that are not free because they need you to engage on their platform like a testnet daily which usually requires gas fees but if you look at this airdrops and this tap airdrops they don’t set a fee that they want it is the transaction fee during the testnet period, this fees are way too low to be considered even a fee but the rate at which this telegram mini app are going I think people will soon realize that they are milking them.
The true airdrops must be free or at least make the payment optional (voluntarily), all you need to do is to complete some tasks, which should not be monetary. Though you have a point, the project matters, like the Testnet and others, but this Testnet of a thing was not like this in the OP, people knew what they were signing for and it was honourable when crypto was still crypto and not how everything was turning now.
Many would even participate in the Testnet and will not expect anything in return because they believe in a project, so it's just like technically sponsoring the project in their little way. But there are too many crooks flooding the internet in the name of airdrops now, especially Telegram and mostly now the TON blockchain. It's just annoying and even their tokens after listing are often worse shitcoins. The success of Notcoin has made them gain popularity but this will soon fade away just like their former ways of toying with people's emotions in the name of airdrops.
