Bitcoin & Cryptocurrencies - proofreading and article writing

I have around half of A4 page of text about Bitcoin and cryptocurrencies (i'm starting a blog on this subject). This is the initial post which needs to be checked for any kind of errors or mistakes and corrected accordingly. English is not my first language. You will also have to do some creative writing and expand the content (especially the last paragraph) so the whole thing is about one full A4 page of text (or even a bit more). I'm looking for someone intelligent with a good sense of humour. The ideal scenario would be if you also were a cryptocurrency enthusiast who follows various crypto related news and twitter accounts. That would help tremendously. If that's the case, you can count on a long-term business relationship, regular work (at least once a week) and prompt payments. Also, when placing your bid, please include something that confirms that you read the brief.
