i support dragon chain now...because etherium has scalability issues which we had seen in the recent time because of some mad kittens... we get to know about a problem when we have serious implications and those mad kittens have given us the oppurtunity to show the scalability problem of ethrium and in long term it would create more such problems..... so dragon chain with both public and private block chains is the ultimate solution.
Yes Ethereum has scaling issues, but so does every other platform that is currently operational. The Ethereum community is working hard to solve those problems and I think they will do it. Ethereum having been launched earlier and had many things built on top of it already, I think it has proven itself a lot more than a lot of other platforms have. This network/community effect should not be understated. But yes, scalability number 1 problem to solve.
