People are talking about a cliff when we go into phase 3 and they are right.
IMHO the solution would be to triple or quadruple the length of the second phase and proportionately lower the maximum reward for that period. That way new miners will still have incentive to turn their rigs to HVC during the summer months and the coin will have a more widespread adoption.
Another problem is the fact that you still can't use your HVC for much, so we need to campaign more aggressively for new retailers.
Maybe devs could use some of the IPO money to create buy support and/or increase bounties? This would also help with the premine FUD being spread (which I sort of agree with, premine IS usually a scam alert, though in this case the coins were sold at a fair price to a number of participants), since at least part of the money would be used for the benefit of the coin.
