I honestly do like the core Block30/HUMBL team. They seem like nice people. If you look through their twitter posts it's all positivity.
Anyway, with some digging through the histories, I found this interesting gem. Calvin Weight from Coinbook explaining what Block3/Block5 ETX token were, when they were available.
But then coinbook closed...
We have decided to close Coinbook. Thank you for supporting us over the past few years. It's been fun working with our crazy crypto community. In the end it was a combination of running out of runway, a bank that was unpredictable, and the risk of balancing inventory ourselves.
Wish there was someway to find the numbers of how it was trading when it was active. Since it's on a blockchain and can never be destroyed, that info has gotta be out there somewhere. Probably in the digibyte ledgers. But that kinda dive is a bit above my technical expertise at this point :D
