Once the asset layer is on main-net, Overstock and other big Hodlers will get it on those exchanges. Ravencoin is going to be HUGE, regardless of the FUD that's been going around lately, and surely getting it on an exchange will pump the coin big time but unless the asset feature is live it will not do the coin or the community any good. I am still mining and on a never ending Ravencoin shopping spree as long as the price is down, and since Ravencoin's final product should be done within a couple of months, I expect it to be listed on major exchanges shortly after.

I expect Ravencoin to explode once the asset feature is on test-net, even without major exchanges, only because once it done EVERYONE will want a piece of Raven
