Can I make money in Forex from home if I have a few grand and a lot of time?

How long is "a lot of time?"

Take a look at the probabilities.

85% of new traders fail the first year. These statistics include some very smart people, so it obviously doesn't all depend on intelligence and capability. Is there something you're missing? Yep, too many things to list here. What makes you think that you will succeed when more than three-fourths of the people trying can't?

From one mentor:

Most traders we speak with have learning curves that have cost them between $15,000 and $70,000 and up to two years in time.

Current online technology allows you to trade Forex from home. You my open online brokerage account, you may transfer money, you may place buy/sell orders. Everything could be done from you home, without going out.

Technology allows you to trade, this is another question whether you will be able to make money. Be smart and do not be greedy.

Only if you are very disciplined and filthy rich you will;chances are bigger that you will get shot in the back of your head multiple times.

Only if you are better than hedge funds and money center banks. You aren't.
