Looking at the DAPP radar statistics it shows that Chaos packs are being sold at .5 cents and up fairly regularly with some sales so you might be able to buy them on HIVE engine or at least buy them a few at a time so you are not stuck with inventory that does not move and flip them for double to people buying on wax that probably are just looking back now and not looking at the actual price on hive engine before buying so they end up spending double the money.
I have not tried doing this yet but I will be trying with a pack or two just to see how long it takes to turn around a sale and if it can be at the price that DAPP radar is saying for the prices on atomic hub.
