What are the products available on the platform? any other use case for the coins?
I already answered a similar question.
Just read our WP - https://www.soy-coin.com/assets/template/soycoin/doc/wp_eng.pdf
Look at the sections: "The Description Of Production." ; "Description Of The Main Raw Materials." ; "Short Analysis." ; "Additional Products And Pure Production." ; "Mining Farm On The Basis Of The Plants.".
what the difference between soy coin and smartlands? or are there any similiarity?
These are different projects. But still there are some similarities
