IMO the current trading level is so low that only the Genesis holders can dump their MNE on you. Take a look at the historic trend line, MNE only spikes when something big is announced (first exchange going live, first announcement ICO) but does not spike when roadmap updates are aired. This means that it is a complete speculative coin and basically nobody believes in the purpose of the scheduled development in the roadmap.
Be fair, through the token release service nothing good has been created and the Pokemon game is a joke. Lottery won't really work considering the low supply so what is in it that would really make sense.
I still keep an eye on it only because MNE is subject to high volatility so if something happens on the exchange level (e.g. Bittrex added, screaming for this for 3 months now) it could be a game changer. Don't expect it will generically increase over time because investors don't think this coin has purpose or a legitimate potential for existence.
Besides, the burning of coins is irrelevant since this has a temporary effect only on the CMG, the coins offered today on the exchanges will not change. Besides the Genesis mining will increase the supply back to 1 mio coins in about 4 months and if any form of development lacks it's back to square one.
On top of this I think that once ART is listed on the exchanges its very doubtful that there will be focus on MNE from the Dev team, sofar most of it are just hollow phrases but I would definitely be proven wrong
Personally I think they should have both companies run side by side. It'd be wise to allow people to invest in both coins using the other, like pay your monthly World App fee in Art, invest in the lottery in Art, fund your ICO with Mne, ...
