I want to grow my bitcoins not by dollar value but amount I have, i've gambled a lot then sold my bitcoins at a higher dollar value but that doesn't work after awhile I used btcjam but I'm not really trusting of the people on there is there another trusted site other then btcjam.com
What about giving goods or services in exchange for them? Like you get any other kind of money. Or you can also invest, which is quite difficult in the bitcoin world, which is full of scammers.
