Someone from the Dev team will be more qualified to answer this one than I am; but I think the main initial diferrences were with the Proof of Stake... I know there are a lot of other exciting developments in the pipeline which will be revealed in the new whitepaper which they are just putting the finishing touches to now, and it's due to be released before the end of this month I've been told.

You've obviously got a great eye for a coin with massive potential and this current dip is a perfect time to buy in x 10+ less than it's already previous ATH which was at just over 2 cents... We all know that's it's going to smash that figure when Bitcoin and all the Alts recover and start climbing back up again... It's just a matter of how long that takes... So I'm buying up all I can at this truly bargain price... and highly recommend you do consider getting in too... I truly believe that there will never be another time to buy COLX this low!

All the best
