the way I increase my balance is by deposits. it usually is my earnings like if I do some micro job online and get paid a small amount I receive it in my freebitco.in account to save on fees (keep my own wallet free of dust) and also receive profit on it. sometimes I transfer my trading profit there too. and sometimes I just transfer my signature campaign earning there which works as mixing and some sort of cleanup (smaller number of transaction output).

Those are great ideas and now I'm considering use some of them for myself. Indeed FreeBitco.in is a site you can trust so why not to send there your micro earnings? Also it's nice to see from your other posts that you are done with continuous gambling and can control yourself and only do it occasionally because otherwise it would be almost impossible to keep your money on a site were you can buy lotteries or play multiplying game. Congrats!
Seeing the funny accusation by stingers I just enabled my lottery for a change. Let's see what happens.
