Actually there are plenty of words to use why you should invest in this platform, but you only want two so for me its the project's profitability and the team.
The platform is a great idea of delivering quality services and goods, that a patient can afford, so it will surely attract many users. More users, investor's profit increases. Atlantico's team is strong, experienced, and stable that works hard and will never let this project down.
Add to that the possibility of gaining profit by being on the platform. With rewards and dividends (which many ICOs does not offer both), it's double the incentives. And yes, as i always point out, the buyback program is always a nifty spec of the project that is really noteworthy to consider.
