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.

(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 60: you get a $80 reward
Steem reputation above 70: you get a $160 reward (2) ByteBall is listed as an official currency on many sites including my favourite, Cryptocompare: https://www.cryptocompare.com/coins/gbyte/overview/BTC

(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
