I mined since the day1 and after mining, been selling other mined alts to buy BlackCoins. I have finally reached 100k BC mark and now I am sitting on it. Definitely not selling any, perhaps buying more if the price stays low. 
Similar to what I have been doing - mining other alts and going BTC -> BC.
To the community : How about setting up a nice bounty for a mining pool that pays out in BC as opposed to BTC? At the end of the day, the pool owner can sell the mined coin for BTC, and use that to purchase BC to payout the miners. This way miners can still "mine" the coin using their GPUs. One of the biggest problems right now is BC distribution, and overall lack of interest. If we can get some GPU miners back onto the coin using this method, it could help out!
If this were to actually work, the hash power alone could floor this price movement with a constant small supply of BTC being used to purchase BC.
This way is similar to mining other coin, selling it and later buying BC
Big difference between doing someone going in and doing that solo, versus a possible working community effort. The former could actually bring a lot of interest. Plus, people are lazy, and they want things done for them. It'd be easier for the user to just connect to a stratum and receive BC payments for their hash without doing any of the in between stuff themselves. Also, when you get paid for mining, it's easier to hold the coin as opposed to mine -> BTC -> BC because then you'll actually feel like you're spending BTC (because you are) and the emotion on your investment becomes a lot greater.
There's just a huge psychological benefit to this.
