I received 211 813 GRC from the Foundation so far, in exchange for our AdWords expenses. Since Poloniex fee is 0.15% for bidders, I saved 317 GRC on Poloniex fees (or 1.73 USD). A rather negligible amount, compared to the losses I've taken because the value of GRC has decreased in 2016.
Since it's well known we have spent 5 USD per day on AdWords last year, you could have done the math too, it's not that hard. I won't address your concerns about a 51% attack because that's plain FUD.
Bitcoin is basically the rising tide over the price of most-everything in this economy, currently. That's primarily why we've been seeing such a price decrease in the value. Coinpayments is a huge step in the right direction because of how it doesn't tie the price of Gridcoin to Bitcoin anymore, and having the website come into fruition at the same time is another great involvement. Can never be too careful about transparency throughout this process and I (for what it's worth, which may not be much) appreciate your transparency among the good work done to bring the site up. I just hope that some future issues could be resolved, such as the possible exploits/vector of attack on the faucet or lack of SSL/https.
