It is only beneficial to everyone that the price is not stabilizing as a common stock would.
The volatile nature of BTC and LTC at current means that people who were very late getting in on crypto (if they're smart, patient, and lucky) can still make a substantial profit with very low startup.
When BTC starts to stabilize and stays stable for a long time (i.e., 6 months at the same price + or - 1 USD), I would consider it a very bad thing and would believe that it would be caused by only a few people having the majority of the available (mined) bitcoins. Once a user, or a group of a few users have the majority of bitcoins available, they are free to manipulate BTC to a certain, dirty extent. Much like the infamous Fontas (known retard scammer) and his lemmings (the morons who listen to him) are very successful with pumps and dumps, the same manipulation can occur by one person alone if he / she has tens or hundreds of thousands of bitcoins at their disposal.
At the moment, the fact that even small amounts within exchanges can cause the price of BTC and LTC to be unstable means that people can at least do their research and sell high and buy low, and make profits on crypto within VERY small periods of time (I made 17LTC off of yesterday's panic selling / buying on BTCE. Not a whole lot, but it serves the point i'm making now).
The price showing any sort of long-lived stability at this point would not be a good thing. The USD is quite stable, but it is both printed and manipulated by a third party. Without putting tinfoil hats on, I don't think anyone in this forum should have a problem thinking up ways this has led a detriment to the U.S. economy and those it affects. I believe this is one reason why Nakamoto set up BTC to NOT be an endless supply. Could you imagine working for someone who held the majority of BTC? They'd be paying you in very small sums of mBTC because they know they can get away with it, just like many employers pay minimum wage for an inordinate amount of work. They understand that if you won't do it, someone else will. Everyone loses.
