AMP has been being developed for two years and is supposed to finally drop in September. The objective of AMP is to pay users for their participation, not really making money for actual posting. The site itself will be decentralized which makes it awesome already. I think AMP is going to be a very successful thing. I would advise everyone to be a part of it. There is nothing wrong with being part of more than one crypto. You shouldn't look at it as a competition. They are two completely different sites with two completely different purposes. Steemit can be successful with or without competition and so can synereo.
