The only problem of iota is the huge supply that it has, maybe if they only have 100 millions max, or 200 millions at least, a lot of people would consider iota as a very profitable investment.
but honestly, if you are a newbie, and you see that a coin is $1,30, would you invest in this one? I wouldn't, only because it is very cheap and who knows if it is going to dissappear soon or not.
If the max supply would be of 100 millions at least the actual price of iota could be more than $10 at the moment, if i am not wrong.
But in fact this is one of the most biggest coins that we have listed right now, i have some iota's on my wallet. once that it gets listed on bittrex it is going to increase a lot, i am sure about that.
IOTA is not going to disappear, it is one of the few projects that bring something new to that able and are not direct copies of bitcoin with just a few details changed, I do not know how successful the tangle is going to be or if it is going to be able to deliver on its promises, but it is certainly a project that is worth watching for and that is worth investing in for the long term.
