That was our original idea just to pay out via the block explorer a percentage, we thought having three pools would generate more incentive to hold but I guess for many peeps this idea sounds too complicated so we will look into this further thanks.
I wondered why you went with the pool payouts instead of percentage, and yes, in theory it could generate more incentive to hold, or provide more coin to those holding smaller amounts ... but in practice, I think it'll be a big headache and overly complicated. You need safeguards against cheaters and physical cards.
I'd still suggest a cap though, which can still be rather big, to just keep exchanges + huge whales from eating the majority of the payouts. I'd also suggest that the coins counted for a payout only come from those who signup to begin with. Otherwise you will dilute the payouts for no real reason.
If you go with the percentage idea, there is also no real requirement for a physical card either. Although it is sort of a nice bonus... just not sure if shipping costs will prove too expensive.
The card is a very neat and as we want to increase BTC infrastructure we thought it would be an added bonus, also transactions form those cards exchanges for euro or usd and sent directly to your card or bank account will generate more long term revenues also for Bagholders and QIBUCK coin.. Some peeps will want to use the BTC others will want to convert and put straight onto their debit/credit card or bank account so with the card it gives them that easy option for very low fees.
