Why I bought some IOTA:
If it works as intended, it solves the scalability problems associated with blockchain.
The partnerships are really impressive and can drive wider adoption of the tangle, which will hopefully lead to token use.
Whilst the devs can be extremely abrasive, there is no doubt of their brilliance.
The roadmap is ambitious, and I am looking forward to seeing what they can do with a second layer solution to introduce smart contracts.
The speed of sending a transaction has increased substantially since I first tried it.
A new wallet is on the way (or has maybe already been released?).
So, I am not going to bet the house on it, but the project is compelling enough for me to dip my toe in. I will expand my position as things progress.
