up to now
after 2 hours of ISSUING TIME(5/30/2014 at 12.00 GMT), 14.6 stakes for total 400,742 NXT, avg one NEM stake=27,455 NXT.
less than 20% stakeholders selled their shares!
cheers!
not everyone sold a full stake... so you could say that >20% redistributed a portion of their stake. which is good!

most of the sells iv seen have been
and if 20 stakes were sold..(just to round it off..)
thats actually only .5% of stakes being sold.. so its actually closer to .3% or something so far! which is good, very few people "dumping".. think its closer to a few smart people "redistributing" part of their stake at low prices for better long term gains on the rest of their stake left over.. this is going really well!!!
less than 20%, which means 14.6 stake of 188 stakes in currency.
