One word "CONTROVERSIAL", its really controversial crypto in 2017, most people saying it as scam and mostly invest on it (including me). But honestly their system really not sustainable, I have doing sample mathematic calculation on excel with all referal interest system, it can collapse anytime. I invest on it since I'm risk taker and only put 5% of my money on BCC, I think as long as BTC prices not going back to $5000/btc that system should be fine. But if 1BTC back to $5000 I think all market will be bearish not only BCC.

I have some tips to checking scam airdrop, here my tips:
1. Look thread starter reputation/rank, it's easy to look at Bitc**talk, when newbie creating ann/airdrop with newbie rank, sure 90% is just scam.
2. I take look on their social media, when account create, how many followers( but this not valid since you can buy followers).
3. Checking official website on google, if created only few month and expired in 1-2 year, I will give it as red flag.
4. Website content, if you found many miss spelling, I think that content build in short time by freelancer.

Let me know if you have any others tips, good luck
