For maximum returns in the long term (x100 or x1000) I think Speedcash is the best crypto buy at the moment.
It is one of the fastest coins out there (as low as 2 seconds transaction time) with key features such as privacy, scalability, very low supply (less than 500,000), private messaging and vaults.
The dev team is the most active I have seen in a while (just take a look at their github) which is obvious by how they are meeting every planned milestone on their roadmap.
Speedcash already trades on 5 exchanges and they are just starting out on marketing and community building now, it is the perfect time to join.
Best thing about this project is that market cap is less than a million.
Awesome right?
