It will probably be the same development as Ethereum. At the beginning the price get dumped over the first weeks. Then it stablized at a low level where it was for a couple of months with some daily and weekly highs until the price get dumped to the highs we know yet. From $0.5 to almost $15. All depends now on the abilities of the devs and managers of Lisk to get interesting and promising projects on the platform, othewise the price will get dumped.
