HODL will not work over the long term, simple economics. If everyone agrees to never sell, eventually the incentive for one party to cash out and sell everything will be too big.
In the start this is okay because people can just buy said party's share, but eventually there is no money left to buy for and then the bubble collapses.
This is the reason why a duopoly in the normal world would never work over the long term. At some point the incentive to break the agreement, dump the price and take all the customers is too big.
I would stay away, there is going to be some bagholders.
