I also did not have high expectations for DOP but at least I was not curious about following the presala with 0.1 ETH, even our group called this DOP INU.
Some have complained about the cost of claiming DOP tokens, whether from purchases or testnet participants. each testnet participant only gets a few tokens, I'm not so sure the price will be very high when open trade.
That's natural because being on the Ethereum network, it will definitely be expensive when claiming, so even the DOP team said the claim process can be combined with a presale to avoid double fees.
At least the 467 DOP testnet rewards they still have a lot of doubts about claiming for fear that the price does not match what is issued for the claim fee.
I was also skeptical about airdrops because of scammers are using it and we don't know which one is good and which is bad at the initial time. Last month there was a airdrop trending and a friend came to me that I should follow him to carry out the task, that is the more people you introduced to sign up the more airdrop you have in your wallet. And finally they were sent to his trustwallet but he could not withdraw them and they were they until they got burn. The time expired, and everything disappeared.
I am not really interested in Airdrops but people are saying that it is very good for them and some people are only doing that. As for me I can't convince people to follow me because the referral process is too difficult because some guys you would asked to click the link would even insult you.
Therefore, you must do deeper research to analyze the project that will be followed and there are still many airdrops that are scams but when you understand, you will know which ones to follow, this is not easy but at least it can be minimized.
Remember that airdrops have a referral program because it will benefit the project to grow with a large number of people participating, it also benefits influencers who have a lot of followers because they will spread their referrals on social media or on their own channels.
