My due diligence:
Tried to find Wazirx’s token WRX on https://etherscan.io , but couldn’t find it. So technically, such token does not exists, which Nischal is promising to give away almost 150 million of them for free.
Nischal promises to list the token on his own exchange ‘Wazirx’ — no where else. So basically its like you start school and give PhD to yourself! May be his goal is to play around with the price for initial few days by leaving only 15% with public, then every time it reaches his target, dumping whatever he holds in the market and make money from people. That sounds fishy to me — so this 15% is nothing but a bait to attract fish to him and then he can steal their money.
I read this article and all the information provided on website, no where I found where the company or its exchange Wazirx is registered and if they have obtained appropriate licenses to operate such business. May be he registered the company somewhere outside India in the wild world of some remote island where no one can reach him. So basically, you do not have any legal recourse if you are scammed by this con-artist.
This is the reason India’s FM Mr. Jaitley does not want to allow people to get in cryptocurrencies because all this con-artists are taking the disadvantage of bitcoin fancy in India.

My piece of advise, stay away from cryptos and if you want to get in — go with established exchanges and last but not least don’t fall for the free giveaways. There is always something you are compromising. If nothing all, then your private information (like your PAN card, aadhar card, phone number, birthdate) which either will be misused by this company or sold to some other scammer who will scam you with all your money.
