Promoting articles with your referral links is okay, but promote a well-known scam method like Bitcoin doubler websites ruins all your credibility.
the first thing I saw was this, I'm wondering which legit service can double bitcoin in 4 weeks? or you have provided some inaccurate information in your article.
If you bother read the article, the article is promoting it's own service. Basically the service is perform trading on Binance on your behalf by accessing your Binance API. However, i have some doubt because,
1. They don't mention what happen if they make mistake during trading
2. It's possible they'll use your fund to create pump-and-dump scheme
3. They guarantee 25%-300% profit each month
