I agree with you. Using the smarter way to connect without 'blocks' as in classical blockchain, and without fees for even tiniest micro transactions. It is just matter of time when IOTA will reach top three in the market cap.
I had diluted my BTC and LTC and went straight for IOTA after reading about their projects. I suggest starting at http://www.tangleblog.com/iota-related-links/
as there you can get a broader view of why IOTA worth investing in your time and money of course. The primary factor of investing in the project was that team gave a huge number of tokens to so-called 'investors' for free as they want them to be a part of this revolutionary new concept. Looking forward to broad adoption of IOTA as they say it is the backbone of IoT (Internet of Things)
I think the tangle is superior to the blockchain and IOTA looks very promising. I'm curious to see if there will be more companies following IOTA and using the tangle. I think you've made a smart move diluting your BTC and LTC and going for IOTA. IOTA has just entered the market and has more potential to make an enormous growth. I think broad adoption might take a while for IOTA, but will eventually come. The transaction time of IOTA isn't what it will be yet, it now takes 1-25 min before a transaction is confirmed and they don't have a marketeer on board yet. I will be posting about IOTA often the upcoming weeks, I thought you'd might be interested:)
