@firepower, I recently attended an event at Facebook Office in Gurgaon in association with PayPal. Although it was focused for E-commerce Entrepreneurs, the host talked about #Whatsapp will act as their major marketing placeholder. It will be a very huge benefit for people who want to sell in India. ICICI having a great customer base in India will power up their campaign to a great extent.

He also informed that last year Mark Zuckerberg had many goals last year but this year he has only one - "Remove Junk From The News Feed"
That is why they banned Cryptocurrency Related ads in the name of avoiding Crypto Frauds. Maybe they will come up with their own.

People & Businesses will stop using FB unless they involve cryptos rather than banning them. So, I think they will explore the technology and adapt like we are doing.
