It's really good to share with others when you find an article that benefits you. Thank you. The truth is, on the Internet today, there is a wide variety of Bitcoin and crypto currency resources. Some are definitely more reliable than others.
One thing which is true is that it's a fact that most of the answers you need are available within the threads of this forum. These threads are pruned meticulously to weed out repetitive posts. I should now, some of my own posts have been removed for this reason. And yes, it's all good. It's also a good idea to try different sites and even the crypto Sub Reddits, which also give a lot of information. After a while, you'll begin to understand which are the reliable sites and which are the ones to which you needn't pay too much attention.
All the best.
