The regulatory landscape, market trends, new blockchain initiatives, significant price changes of well-known cryptocurrencies like Bitcoin and Ethereum, as well as adoption by traditional financial institutions or businesses, are some of the common subjects of interest in the cryptocurrency industry.
Also Remember:
When making investing decisions in the unstable cryptocurrency market, keep in mind to check the veracity of your information sources and to proceed with caution.
I don't know about anyone else but my major source of information is bitcointalk. This forum has experienced members in almost all sections of the Bitcoin space. From my little experience, there have been questions that have not received some helpful answers. The worst thing you will do is to get information from social media. These platforms can come up with different false information that will only lead to FUD.
You have to also be careful of the so-called crypto experts. Many of them know little or nothing about bitcoin but their intention is to promote Bitcoins that will end up becoming worthless. Don't also follow the predictions or hypes of some celebrities because they were paid to promote these projects and cannot guarantee their credibility. If you think that you have to be cautious when investing in bitcoin then you should be extra cautious when dealing with altcoins.
