IOTA has 0 fees on transfers.
IOTA theoretically in the future will be near instant transfers(even now they're still very fast)
IOTA is quantum proof, something future cryptos will have to resolve.
IOTA has a HUGE team full of very smart and proven individuals.
IOTA has a very large total supply which eliminates the physiological aspect of "Buying at a high price"
IOTA is decentralized
IOTA has a pretty decent following with 31K reddit subs, over 37K combined twitter followers,30k+ slack members and it doesn't have cult hate towards it like coins such as Dash and Ripple does. Unlike other cryptos Iota forces companies they partner with to use
IOTA 
.
IOTA had no premine or anything, but they have a foundation were you can donate and 5% of all iota was donated after the ico and iota just legally got known as a non-profit organization so they can now legally spend those funds on new developers and marketing
The problem most blockchain cryptos face is scaling. Iota fixes
that with replacing Blockchain with tech called the "Tangle" that can handle unlimited amount of TX/s. The tangle is still in beta phase, which is why the marketcap is only around 2bill and not 100Bill, in my opinion that is a high market cap for a crypto still in beta phase and that shows huge strength for the coin considering it has the WORST user-friendly interface and noob friendly crypto out of the whole scene. There are only currently 3 exchanges that deal with IOTA two of which recently just added it(Bitfinex,Binance and OkEx) which means once it gets added to Bittrex it's going to go nuts and their is signs of that happening soon(Devs announcing a huge announcement soon and bittrex following iota on twitter.)IOTA has partners with multiple HUGE companies such as bosch and Sopra Steria which can be found here: https://steemit.com/iota/@nateq/every-partner-and-affiliation-that-iota-has-the-tangle or here:
The cons of this seemingly amazing cryptocurrency is that as it is currently still in beta phase the devs have something called the "Coordinator" in place which gives slight centralization to the developers but enabling the coordinator when you run a full node is optional so this will slowly go away as the project grows stronger, making it Decentralized. The official wallet is complete ASS, one of the worst if not the worst user/noob friendly wallet, but a brand spanking new beautiful wallet is being released within a month. Here is a image of how it will look:
It isn't listed on many exchanges to buy it, but as i said earlier it will be accepted on all the major exchanges hopefully in the near future and bittrex might happen soon. You can say this is a pro rather than a con having it only accepted on limited exchanges as you can buy now and it would most likely rise once accepted on other high volume exchanges.
Would love to hear everybody's feedback with proper points and facts as of right now i'm holding a large position with iota as i'm not very good with the technical sides of things or code but i'm betting that everybody's ignorance and money hungry minds are blocking iota out of their heads as this coin is a ultra long hold due to it only being in beta as of now.
