The best sources of information about Bitcoin are:
1.Reddit : Reddit is the 9th most visited website in the world.
2. Twitter : We may thank President Trump for turning Twitter into an endless source of amusement, but the popular social networking service where users post up to 140 characters long messages is also an excellent source of Bitcoin news. People who post on Twitter can make their posts more visible and easily searchable by using hashtags, keywords prefixed with the # symbol.
3. CoinDesk : CoinDesk is a popular cryptocurrency news site famous for its CoinDesk Bitcoin.
4. Cointelegraph : Cointelegraph is an independent news site covering everything from cryptocurrencies to blockchain to the internet of finance.
Yup, you are right. But the sources should really be checked before believing anything you find from all the choices you have mentioned which newbies might not take into consideration because there are a lot of fake news out there that can really lead newbies astray from the truth. Even in this forum, there are a lot of people that posts or shares fake news that they, themselves haven't even confirmed yet.
