so i decided to sell my 0.01 of bitcoin which i sent to localbitcoins.com. when i sent the ammount useing my phone it said that there would be a network fee of 0.00. but the ammount of bitcoins that my localbitcoins account recieved was 0.00003701. so is there something wrong? the address is 12XRDVMNocazHN5WLCX29aYrmDAtcUC2dF.
any help?

So I've been mining for about 2-3 months non-stop using 4 antminer U2's and when I first started out I was getting a little over 0.00002000 BTC , now I'm only getting 0.00001300 is there any reason? I'm using a raspberry pi as the controller hub all of my miners are at 2 giga hashes and don't really fluctuate. The only thing I could think of is my pool which is shush pool.
Please help!

so im mining bitcoin through my raspberry pi and i cant figure out how to over clock it
i have 4 antminer U2's that idle around 2 Gh/s
i would like them to get up as i have overclocked them through my computer on cgminer
but the raspberry pi is different then just using a normal windows terminal
 i tried adding the "--set-device antminer:clock=0B81" to the end of my launch command but it dosent overclock
any help? im verry new to this >_>

heres the code im using
screen -S Mining ./bfgminer -o stratum.bitcoin.cz:3333 -u USERNAME -p PASSWORD  --set-device antminer:clock=0B81
(obvously im withelding my mining info from the launch code)
