I bought my first crypto in 5 years just a few days ago, IOTA. I feel that IOTA is a step in the right direction, avoiding the competing priorities that blockchain based crypto results in with miners vs users.
A bit on that in this article:

Also potentially in the process of breaking out:
Something we agree on for once again in a rare while BB

I was somewhat of a critic when Leo first bought this one to my attention a while back, as we were both being pretentious little bitches towards each other at the time, well I was at least.
I must admit that I couldn't see past the inhumanity of this one, the Tangle was a tad confronting and the complete independence that it operates in was a bit Borg like for me until I got my head wrapped around it.
But then I'm a bushy redneck type and don't even trust any of the people on here, let alone bloody machines that can communicate between each other.
It took a couple of humble message exchanges from my end asking Leo about Iota before I got on board.
It is an extraordinary schism in Blockchain technology to say the least, Especially when most people invested in Blockchain right now don't even understand what they have their hard earned invested in when it comes to mere Blockchain technology itself.
The IOT is a field akin to when the internet itself first evolved, those who can remember the sound of a modem connecting to a plain phone line back in the day are far and few between now, most didn't even know that it existed when that sound meant something.
Now My 8 Yr old is complaining that her satellite wifi is being interrupted by cloud and storms , and her download of Dance Academy is slow. Complaining about why she is getting notifications from something called Zero hedge on my account and chucking a spaz when told that DATA IS MONEY.
The Internet Of Tings(sic) might sound like the prequel to the Terminator, but your phone does it every few seconds or less, your computer does it every few milliseconds, your whole life is surrounded by manufactured products that open and close doors, adjust temperature, tell you where you are going, book a cab, make a reservation, suggest a movie or meal, wash your clothes, alert you to a message on this that or the other platform of your choice.
Iota is not the same as a pure blockchain protocol that exists for Humans, it is designed for things. As such it can and will validate a Job done, a temperature reached, a transaction completed, a product produced, a door opened, a package sent, a load of laundry washed, a car cleaned, etc, etc, etc, etc, etc. Any and all menial or machine task assigned will be completed and locked into the system as such. But it will also be followed and recorded for future evaluation.
