Also some week back, another long running gambling site's Fortune Jack Signature campaign (if I remember it correctly) came to an end. I wonder whether the bull market and increase in the bitcoin prices have anything to do with this or if it is just an individual gambling site's decision to pause the campaigns temporarily or permanently.
I don't think that the decision to end the FJ signature campaign and the Freebitcoin campaign suspension is somehow related to the trend on the market. There are other reasons, and we should pay attention to why TheQuin has not been very active on the forum in recent months. I guess there is probably something going on inside Freebitcoin.
For sure, the price of bitcoin has nothing to do with the suspension of the signature campaigns as all these signature campaigns are paying Bitcoin in terms of dollars. Yes, when the bitcoin price is high, the signature campaign participants will get the same amount in USD but they will get fewer Satoshi's.
I believe that it is the decision of the companies whether they want to continue or hold the campaign and no one should have an objection on it. The companies better know how much they can afford to invest in marketing and what the return on investment (ROI) is for them in certain marketing techniques.
