Developers were very smart to price the IPO so high that it eliminates any potential short term pumping and dumping. Likely this won't occur and you need to hold the coin long term. This IPO is not for people that wants to make a quick buck and this should be posted in the OP.
But you can't prevent the miners from dumping
and you can't prevent people from buying again only 8btc of dumping a day not all miners dump. seriously if you feel threatened by 8btc hahaha
