If there was anywhere as much manipulation as I get suspected of, I'd be way richer. It's far harder than you'd think.
Fair enough.
If you have money, there are probably better ways to spend your time that are not necessarily related to attempting to increase your holdings through trading, but also sometimes, there are fairly big players who develop systems to trade and you can tell by looking that some folks are trading a lot of coins.. but maybe sometimes they lose money, too..
Anyhow, maybe that trading is not a great way to spend your time, even though you may want the price of BTC to either stay steady or to go up in order to either preserve or to increase the value of your holdings.
