hello,please suggest me. how can i find good upcoming airdrops??
You can check it at the announcement thread and bounty thread here in the forum if you have all the time to browse each of them to check. The easiest would be visiting airdropalert.com for the list of upcoming and ongoing airdrops that you can participate.
I am visiting the site you mention and I think the site giving the information about a new airdrop and I think this could be our guide to choosing the airdrop. I think we can join many airdrops in out there so our chance to make money will bigger and we can collect much of coins from the airdrop. besides that, we need to choose only the good airdrop by reading about their projects so we can decide what airdrop that we want to join.
