but before writing more articles I'd like to have some opinions about the first article.
There are some errors in information you provided (I suggest that you do more research [technically] prior to publishing an article since it gives the wrong idea to those who read it [especially new
BTCitcoin users]).
I don't want to give technical info as an expert. I CAN'T. I'm not a expert.
The first half of the article is on the technical side (a bit), in which you had the errors.
I'm going to write news and monetized simply explained guides.
Perhaps that would be best (to have news articles). If you ever want to have some tutorial (guide) of some sort, make sure everything you provide is correct.
Honestly speaking, there are way too many blogs on the field you're trying to get in and it would be best to only continue this journey, if you have something new to offer (since most users will continue reading the other blogs and as result you won't have any significant traffic).
