OP wrote it as like it's two different thing but Medici Ventures is belong to Overstock. They are the same thing.

So, Overstock C-Level got interested in Crypto so much, they couldn't help themselves but to create a coin.

They say, no premine, no ICO but I'm quite sure they kept the mining rigs ready to dominate the game. After all, when mainnet gets launched someone needs to keep the network secure(!), am I right?

All this Binance and other exchanges happening because of Aggressive Marketing/Branding push by again, Overstock.

They got immense amount of experience in Business, I have no doubt that Overstock will do everything to make sure Raven stays relevant and popular.

Regardless what they do, Raven is a scam. A scam by Overstock. Anyone can contribute the network sounds like a bullshit to me. I'm sure they can but Overstock will keep the control all the time.

Long story short: Without Overstock, this coin is literally DEAD.

Token launch on platform? Sounds like C-Levels got super greedy want to achieve same success of Ethereum. (make no mistake, Ethereum is a scam too)

Community looks solid, algo looks unique, nice UI/Design but Overstock most likely the majority miner, dev teams probably getting funded by Overstock.

So, Meh. Just saying... Good luck though.
