Re: [OPEN] ⚡BQT Signature Campaign | Member - Hero | 0.0007 BTC /Post ⚡
I think it's because there are more participants in IOU than BQT so to maximize the campaign they decided to increase the limit. 
I don't think they want to maximize the funds per week 'cause in the first place, it's been expected that there are a lot of participants in this kind of signature campaign so I think IOU will stand more weeks before the ICO ends. Who knows?
