Ravencoin is Bitcoin but with priority of future commits prioritizing assets rather than being cash or digital gold.
But there is already a lot of coins with smart contracts option. Why would they choose RVN instead?
Because the others are old tech. Raven is crypto v4.0

Jokes aside i believe it would be because of Raven's decentralized nature. All of the other projects have known CEO's. Raven didn't even send somebody to create an official(!) ANN thread ffs. They don't sign contracts with the exchanges. All is community driven. If this is a bad thing or not, it is up to you.
