What if we bought POSTokens for multiple times? For example, I bought POSTokens from EtherDelta twice, do I get the bounty for each trade or for a specific trade (like the first one or the last)?
You can buy as much as you want as long as you bought it after the trading bounty went live, also note that all POSTokens you sell will be subtracted so you can buy multiple times if you want, just make sure you don't sell.. give it a day and check the reward list you should find your address there ^^
