I open this topic because i want know the opinion of others and also to help other to decide
Right now IOTA should be worth a buy.
Primary reason is that it is indeed a currency without any sort of transfer fees since it is not blockchain based. Also, it has 0% inflation. The ICO went pretty much under the radar of everyone, and price right now is low(below $0.5).
If you can hold that for long, you should be in for a treat.
