Hi @vihanehal

Hopefully I can try to answer some of your questions..
(1) As far as my research goes, the Byteball crypto news is correct.
(2) ByteBall is listed as an official currency on many sites including my favourite, Cryptocompare: https://www.cryptocompare.com/coins/gbyte/overview/BTC
(3) It is not necessary to have a reputation above 30 to be eligible; The airdrop is rewarded to the following Steem accounts:
Steem reputation above 30: you get a $10 reward
Steem reputation above 40: you get a $20 reward
Steem reputation above 50: you get a $40 reward

Steem reputation above 70: you get a $160 reward

(4) You can join right now using this referral link: https://steem-byteball.org/#GVJRIQ6SY7HRYODFCLKY6JVZBYFFNIJK

Anyway... I hope that helps you get onboard.

Thanks for the great question!! ~ThiNXx
