got more around 20 airdrops in myetherwallet so far. not bad at all. if we keep an eye on new airdrops and participate, most of them will send you tokens, in my experience. But few of them are scams. Never send donations to airdrops that send a google form, or share your private key with anyone, even if they claim they don't store it. Keep a spreadsheet containing important details of each airdrops you participate, so you can effectively manage them. check the telegram groups regularly and participate actively on them. Be active on bitcointalk as well, that will improve your credibility when attending airdrops. If you got enough time and ready to work hard, you can attend bounty campaigns as well. bounty campaigns fetch you more tokens than airdrops.
