I was turned off upon checking your article. As I read, there are pop-up ads that's coming out from side to side and there are permanent ads on the right side which I think is sufficient for your ad revenue.
Wow, you don't use an ad-blocker? How can you even browse around without one? Every time I temporary disable it I feel like I can't see the articles anymore and is just ads.
I read the article and it offers fairly solid advice. I would be very wary of the wallet they're advertising though. I don't know about their mobile apps, but the direct link lets you generate your wallet passphrase online within your browser -- this is incredibly risky. Again, for visibility: I strongly suggest you ignore the wallet the article is suggesting.
This was my impression also, if you're going to tell people to own their keys and you might want to suggest more alternatives, and coin.space is not really the most trusted wallet out there, they did have constant development on it since they took over but I will stay away from it. The article would have been better if it would have offered mulptiple alternatives and a comparison between them, especially the weaknesses in it, since a feature might save your seconds, a weakness will lose all your money.
