Alot of the mainstream news articles in this space are really either too biased for or against the technology and future side of things.. so that part really makes me uneay.
Most of the information I accumulate off of each coin and the technology comes from the whitepaper, a few people I trust on youtube, or headlines from twitter (although all of these things have to be taken with a grain of salt).
Future of blockchain I'm still searching for with some quality content and will be revisiting this thread for information articles or pieces dealing specifically with that..
Investing is a tricky one.. as a position/day trader who only hodls bitcoin I find charts to be the best use of investment advice of whether something will pan out or not.. obviously in the future all these coins and investments can't maintain a floatable value and "shit coins" as they were will eventually goto zero, but as of now nothing that is bled out enough from all time highs wont yield you money as long as you are too greedy.. The one caveat is if the news/technology/excitement/unique idea information of a coin is all good, the coin may be worth holding longer since it may have a higher market cap ceiling. I would use a coin's twitter feed/whitepaper/telegram to get 80% of news around these types of decisions and a few youtubers again and maybe sprinkle in a medium write up on why this is a good coin.
Others:
I really like Datadash's information on youtube, his coin picks are obviously biased and should be taken with a grain of salt but he taught me a lot about moving averages and seeing things in a more long term perspective instead of just on 1 hour charts..
Quickfingers Luc youtube channel taught me alot about safe zones for day trading that have helped my success quite a bit.
Telegram telegram telegram, people are a great news source.. even what they dont want you to pick on behind their nonstop shilling or fear as a group can help you avoid bad projects or atleast wait for them to go down more.. (sounds awful to say, but usually ignorance, fear, and panic will come out no matter how much people try to hide it if they talk to you enough).
Good post with lots of interesting stuff, will be revisiting this post for some articles about the future of blockchains and how will proof of work specifically look 10 years or 100 years from now.
