Come June 14th, those users who invested probably about 10-50 btc will all dump their WAVES and profit about 100%. Lets say someone invested about 10btc on Waves so he now double up to 20btc after dumping. Come halving, his 20btc will also turned 40btc. That's about 300% return. Will he buy back WAVES? more than likely NO. seeing he already squeeze a lot of btc during the release. it may take a year before WAVES will ever recover just like how Lisk turned out.
But he may possibly buy RISE instead to once again dump.
