I must say, I have my doubts about this ICO.
Who, outside the MNE community, would be willing to invest their ETH for tokens that then takes them 60 years to receive?
I wouldn't .. unless I had a shitload of ETH!
Hodling is one thing...but 60 years?! Most of the investors will be dead by then.
I did believe in MNE, but it will most likely spike before the ICO, and then die off.
If you buy ART and its start mining each day while this coin takes it to the exchanges you have an opportunity to continue selling you coins until your old days!
If you invest 1 ETH in 1000 ART and the supply grows with the increased availability of coins it can be massive since Dev raises money to get this one listed a pretty much all the exchanges.
1000 ART could suddenly be worth 10.000 USD (take MNE in the early days) but if you invest 10 ETH you will have 100.000 USD to mine over 60 years.
It comes down to the question are you willing to take the risk but reap the benefits?
Will 10 ETH by worth 100k USD in 60 years? Or will ETH only be a subject in the history books :-)
For now it would be good to invest a little ETH to purchase MNE and use these MNE to buy into ART. At the moment this is still a better option since it's cheap compared to ETH when you buy in this ICO next month.
It's an interesting concept and who knows where it will end up!
