There is no certainty in any airdrop, we just have some little faith in the project due to their effort and transparency. I am not a fan of airdrop, but since the lunch of Not coin, other telegram airdrop projects have shown in the crypto space but only Hamster turn out to be the most popular due to the number of participants they are having on a daily basis. If it turn out to be scam, it will ruin almost all the telegram based airdrops, and since there is no money involved, it will not pain us much, just the wasted time and effort that is not paid.
I agree there are literally hundreds of airdrops because its one of the easiest to do to get a new coin instead of buying it in their presale.
Some tasks only involved following the platform's social media handles in the case of Hamster and Notcoin what could be easier than tapping your cellphone to acquire their token and with the success of Notcoin its ushered the coming of many tapping mining concept and Hamster got the attention of those who seeks these new concept of tapping mining, its a case of Hamster launching at the right time so they become the top trend this year with 54 million subscribers.
