You can let the big boys play to lose their money and make a profit doing nothing but transfering money or BTC to it, you know. So, I wouldn't say everyone loses. Only gamblers lose.
Do you actually do that yourself? And do you manage that actively or you just stick in a pile and let it run?
Since I have absolutely no clue about speculation, yes. I sent BTC to Bitcoinica, exchanged at a relatively high price, earn interest on USD. About 10% currently. Additonally, I keep some BTC there to get mini-interest and be able to sell more if the price goes up. No maintenance fees whatsoever. As for active management, I check my ledger now and then to see if my interest payments are coming in as planned.
