Look at this and you'll find out what's IOTA about

Investing or not it's a personal decision but If I may give you an advice try to get to know everything about the project (some projects ended up being scams) and if you think that it would be a good acceptance from people and the project would be usefull in the future just then you may think on investing. Taking that decision it's not just about holding the coins and waiting for it to magically earn some profit.

The fact that a coin goes up or down depends on people's interest. So if you are exited about IOTA as I'm look at the link, learn about the project and then decide if you want to invest :)

I bought 90 IOTA Tokens today and plan to buy more in the near future.

I hope this helps
