here are a few suggestions at a glance
First, it is always better to use your own original article, rather than to take it from other sites. you are always the second to post something and Google threatens you as less unique. DaveF is already explained well.
You need to improve your on-page SEO. you are missing many things, things important for Google ranking. For example, you haven't Google analytics.
Your content is not SEO optimized. Research more about "thin content", it is very possible that this is the reason why Google is pushing you aside.
Also, you have some mess with meta and H1 tags. somewhere you miss them, and somewhere you have too many.
some of the page links are too long, search engines don't see it as friendly.
for example,
https://www.cryptoinfowatch.com/the-third-richest-mexicans-advises-followers-to-buy-bitcoin-when-the-price-is-lowit looks like you have the Yoast SEO plugin installed, but probably not well-tuned.
of course, backlinks from domains with high or solid ratings are always appreciable.
