"mtgox make money out of you trading and someone has been made rich out of these people losing money"
yes, exchanges take trading fees, so every time someone buys/sells they take about 0,02%. They do make a lot of money this way. The ones who got rich out people losing money are the hackers that stole the Bitcoins from the exchange. Gox themselves are now in a little pickle and have to face court.
"Being able to print more money is one way of controlling the value of your currency. You could also argue that you could make a faster car if you remove those pesky brakes, but brakes slow you down safely rather than instantly stopping when you hit a wall"
Money printed is either bank credit (loan money (interest)) or non backed up money created out of debt. Inflation and deflation can be regulated, but i think this system is not going to be good for the long run because it will only push problems forward. The economy will eventually crash again and repeats. I'm sorry i don't really get ur car reference ^^. A currency does not need to go faster but must transparent and predictable.
"There are already enough people that the prices aren't being manipulated by one person"
Haha, have you been to the exchange? If you own a lot of coin (and not talking about multipultimillionairs) and put up some buy or sell walls (to your intention) u can guide the market quite easily. A pump and dump scheme is often used: create a lot of real and fake (no intention to be filled) buy orders with bots so the market gets exited, wait till the price spikes and dump everything when it gained a few percent upwards. A volatile market is very profitable for these people or groups and therefore the coin is highly manipulated to remain this way.
"The problem comes when you have a lot of people with a relatively small investment because a large number of them might start selling their couple of BTC at the same time"
Not every Bitcoin user is active on an exchange or is a trader, but i agree at the moment most of the new people are investors with weak hands. The more Bitcoin kept within the system by different non speculators (decentralized) the better and more stable the market. Big funds moving in, even like banks and wallnutstreet would be better indeed.
Unfortunately the coin is now viewed and used as speculation instead of a currency, i wonder IF this is ever going change though. It has proven to be really hard to predict what it will do
. I do think it's here to stay for quite a while.
