I've been trying to soak in recent events and attempting to make up my mind about it all. The truth is that hindsight is always 20/20 and a post mortem analysis is never too hard to come up with, but I'm too tempted not to add my two cents to the pot.
It does not take much for you or I do go down the rabbit hole here, and try to follow the logic as to how LUNA failed, how when the PEG broke, everything broke, but putting all those facts aside, to me the simplest way to analyze it is this...
How centralized was it?
Which is the question that we don't ask ourselves often enough to be honest. Yes, centralization/decentralization is a spectrum, I will grant you that. But, at the same time, it doesn't seem to be that there was much decentralization happening.
The fact that the CEO of Terraform Labs had the power to use the funds to buy Bitcoin to ensure the value of the LUNA token, suggests to me he WAS the currency. It was not done by smart contracts as far as I can tell, but more calculated decisions by Terraform Labs.
I'm trying to say
There is no project that is failure proof, none. Not even Bitcoin as much as we put it up on a pedestal, but if there is a project out with catastrophic single points of failure, then it's not a matter of if, but a matter of when.
To apply it to our environment, to Hive, because It's relevant for us, the users of this platform. It seems to me that prior to Hive evolving into what it is, this environment existed on similar dynamic. 
The more I think about it, the more I'm confident of my investment in this platform. Not because it's perfect, we know well it's weaknesses, but because it's battle tested. It's survived terrible decisions from people with centralized power, and one would even argue continues to prove it's value and potential.
What's the lesson?
The lesson people never seem to learn is simple: If it's too good to be true, then it's not true.
But it doesn't matter how many times we say it, how many times it's posted, how many videos someone makes about it. People will buy into things without understanding it, and sometimes they will get lucky, but most of the time they'll get burnt.
Did I learn the lesson? Well, I too got rekt once so hard, I still feel the effects from it. I would love to say I know better, and for the most part, when I'm presented these "amazing projects" I analyze them with a cold heart, and thus stay away. But, I know better than to say I'm above being scammed.
I feel terrible for those who lost everything. Yes, I know it's their fault, but being someone who got pulled into a scam once, I can empathize with drunken stupor of believing this is your way out of the rat race.
That being said I can guarantee one thing. Terraform Labs won't be the last of it's kind. Plenty of stable coin projects come and go, and the cryptospace is mostly scams still to this day.
Not that someone needs to listen to advice from me, but I have one mantra I keep on repeating to myself: If it doesn't make sense, might as well be shit, no matter how many people eat it.
Harsh, I know, but so far it seems to be working for me.
