I would choose None of the above, although I am not tracking Lisk developments so I am more or less ignorant about it. I also stopped tracking Dash's developments.

Monero might have a shot just being a robust highly respected alternative to Bitcoin's scalepocalypse.

Zerotime does not scale. It scales O(n^2). How many times I pointed that already and I am tired of getting into long fights with all the Vtrash fanboys who apparently don't understand technology yet are so sure that the anonymous "JConner" is phenomenal. Stop fighting with me boys because I am not going to trash your trash again. Waste of my time. Who takes seriously a project with a single anonymous developer who doesn't even write proper white papers. Most all of the altcoins are bad jokes on those gullible enough to purchase them. If you are just speculating on others buying the trash from you at higher prices, okay fine, but pleeeaassse stop with the lies about technology which you don't know enough about.

MaidSafeCoin I trashed recently. Ditto Iota. No need to repeat myself.

Posts like this makes everybody hate me. I think I will STFU about other coins, until or if I can offer something which they can also attack.
