Don't give up, it does get through to some people. I used to be one of the 'hate all altcoins' bitcoin holders until this month. I got so tired of seeing bitcoin decline, and reading about how all the new mining coins coming in every day were hurting the price. When I read about bitshares, and how it attempts to be an autonomous company that actually makes a profit that is returned to holders, instead of bleeding money through the expensive mining process, I became a convert.
A dividend paying asset is far superior in the long term to an inflating currency! That is the key selling point. And bitshares has the best name to drive this home. Bitcoin is the currency, Bitshares is the asset!
I'm now in the process of converting 1/3 of my bitcoins to bitshares. (Not ready to go all in because bitcoin is still so much larger and thus less risky. If bitshares is indeed better, then my holding of it will grow in time to surpass my bitcoin holdings).
