I guess you could check the timestamps on the blocks to find out if there were any spans of time during which BBQcoin was "forgotten about",
My impression was that it was pretty much always running, even though probably most people who ran it just CPU-mined some number of coins they felt were enough of a stash to store away against some possible future time when the coin moved on from the early adopter CPU-mining stage to being dominated by GPU miners keeping the difficulty too high for CPUs.
Like Satoshi said, it makes no sense to ever delete a wallet, just stash them away in some dusty old repositories of backups in case some day they ever turn out to be useful. Since it is not old enough for even floppy disks people might have backed them up onto to have degraded from age it is pretty safe to say the vast majority of coins are surely safely stored in wallets in case they are ever worth the time it takes to go rummaging through your stashes of backup media looking for the disks or USBs or whatever that you happened to stash those particular files on.
I also know of lots of groups who have BBQcoins on their books at whatever nominal value they feel reasonable to list them at, as just another part of their inventory of assets.
I have not yet added the collated data to my
historic tables and plots of asset values because I am still watching what values the collation routines obtain for that coin to get an idea of whether they seem sane before going to the trouble of pouring them into the archives of value and adding them to the scripts that build those web pages from the archival data, but for example right now I am being told the value is 0.96408952 DVC per BBQ.
That means I could probably pick up a few million - or maybe even several million - of them for that price, but I suspect as players start hearing about some outside the game exchange(s) offering better prices they are likely to start increasing their ideas of how much they are worth.
For comparison, the same cycle of value collation claims that GRouPcoins are worth 0.05756194 DVC each and I0Coins are worth 0.04324450 DVC each, so evidently BBQcoin are already imagined to be worth more than either GRouPcoins or I0Coins though not as much as DeVCoins.
