SEO here.

Anyone who promises to rank you at the top of Google is bluffing just to get your business. Nobody can promise to get you to the top of Google except Google itself. Since SEOs don't control Google, the best they can reasonably promise is to implement all the known best practices in order to boost your site's rankings.

It's also important to note what "the top of Google" means. Are they ranking you at the top of Google for keywords which no one is using? Or are you ranking for keywords which are actually valuable?

Most of the best SEOs don't work based on results. They charge a monthly fee, which they can back up with a portfolio of demonstrable results. And they usually charge more than 1BTC as well.

If you've invested 30BTC into this project of yours, you may want to take a step back and reevaluate your business plan. That's a lot of dough without seeing any results. I don't mean pull the plug altogether, but you may need to pivot your strategy to take it in a more profitable direction.
