As the Crypto community is still in it's early phases there is no clear established authority to confirm the news.
For example if you read any general news published by BBC, CNN or NY Times you know it must be genuine as they would have done their research.
Another problem is news spreads very fast in the crypto world and sometimes it's difficult to judge if it is authentic or fake or worse even a scam.
A recent case is there was news that Tunisia had finalized to move it's currency Dinar to crypto blockchain based.
Immediately the news spread fast saying great move and achievement by an African country.
Now there is a report it was fake news.
So be very careful when you receive any new update, don't take any hasty steps and wait to confirm it from multiple sources.
