i would not join any airdrop need send ETH ....
I was cheated by a airdrop project

I want to join Airdrop. But, how do I transmit 0.003 eth? while the token in my wallet is still empty?

airdrop that must send transmit 0.002 eth without filling out the form and wait for the distribution is good enough because it can neutralize the bot account but this way is also less effective because airdrop is usually free at no cost ...
how this coin percentage with eth ,,,
we can not know because the least informsi ...
Because I do not want to collect tokens that just become garbage

If as many as 10,000 participants donate 0.003 eth means you will get as many as 30 eth. it is a huge amount and will make you very rich. but unfortunately there seems to be no one to donate. 

Where Docs sir ?? And how register to Airdrop ?

How to join....  Where is link please!!

There is no form to fill, no spreadsheet, this is automatic.
- Exact 0.003 eth needs to be sent to the smart contract address: 0xF5Ac04111dfeCaf859071C4a424eBcdA1379825b
And you will receive your token immediatelly.

You can check the smart contract, the source code is public.

In my opinion, the details of the project cannot let me pay 0.003 for it

The airdrop mode seems nice but i will not send eth for a token that doesn't have any project behind it.
