So here's what I'm thinking. Ken has two solutions to the shares issue with coloured coins number one and CT a fallback option. He will continue to stall the CT option in favour of a permanent decentralised solution. That is excellent and is telling of Ken's long term aspirations to make this company a success. The day he gives off signals to the contrary is when all hope is lost, until then we are still in the game.
Regarding the technical side of things of which I am almost clueless, I recall that BFL also changed their engineers for similar reasons that Ken has given. They seem to have got over that hurdle which didn't sink them. Now perhaps we are assuming that changing engineers means we have to go back to square one but surely the second firm might be able to build on work already done? Also we don't know how long the second firm have been on board (no pun intended ) and how close they may be to completion. Add all that to the quote below and I'd say once we negotiate with Ken to release more details there's every chance we look back on this episode and realise 'mass hysteria' sucked a lot of us in. Now before you flame me, I am only sharing my opinion and have a very positive outlook on life. My cup is always over half full and if you lose hope then you throw away any remaining chance of success. This is from the most legitimate person in this thread due to his inside knowledge who is willing to post.
