Be warned that many will consider this merit begging, but like the other two people that gave you merit, I haven't used your BIOS but gave you a merit anyway because I am sympathetic to your plight.
The problem seems to be that the altcoins/mining subforum doesn't get a lot of merit distribution, despite that it has a very high signal-to-noise ratio and is generally free from the useless sig and bounty campaign spammers. Not much you can do about it except bring attention to the issue here in meta (though, again, be warned that doing such can backfire by getting you put on ignore).
Its indeed very bad there...I can name quite a few people there that helped community a lot and got near zero merit, and I saw
posts like "BTC is the king, all altcoins suck" get tons of merit
People like nerdralph, notbatman, doctor83 and few more did lots of stuff for free, with not much award...its either lack of merit sources there
or that subforum tend to collect lots of misers
Personally, I'd like to see advanced system like Anoraks forum use...not sure what forum software it uses, but I think I saw it somewhere else too,
so its not proprietary...it has very developed automatic reward system (plus ability that users say "thank you" manually too)
In my example, I'd get reward for "link clicked 20, 50, 100, 250, 500..." times automatically
