FUD for Thought:
1) The paltry supply cap can't run micro transactions or the IoT if you can't send decimals of IOTA, which AFAIK you can't, so this is going to be a very serious problem. I'm hoping they can simultaniously increase the supply and holdings in wallets without royally screwing up their image/brand and pissing everyone off. (Please comment if you know how they are dealing with this or if I just flat out got it wrong!)
2) It's currently centralized, but they claim it won't be sometime in 2018.
The rest of the tech is looking great and I'm AF on this one as a long term hodl.
