Earn money by buying and selling USdollars?

you can in theory make money this way but you should ask yourself if you really want to be holding fiat money when the world's central bankers keep printing more and more of it, making it worth less and less.Perhaps if you are determined to carry out this business plan, you could buy the dollars from tourists or at a hotel.If you buy them through bureaux de change, they will take a percentage commision from every transaction that you do with them, greatly reducing any profit you can make from this. They also won't give the same up to date exchange rates that are quoted on the international markets.Why are you not trading physical gold and silver? I have heard that the Indian market for these commodities is huge.........

I call this Forex trading. Look easy (in term buy cheap, sell high) but in fact is really difficult. You must calculate several factors before you decide buy or sell currency. You need to learn a lot before you involve in this business.

I have done something like this in my home town a little while back, and I was able to actually make a fair amount from it. We have three foreign exchange shops in my home town, and on one particular day there was a different exchange rate between dollars and pounds, so I changed the £100 I had on me into dollars in one shop and then walked to the other and exchanged it back into pounds but obviously got a bit more; and then kept going backwards and forwards for two hours until the rate at the other shop caught up. I ended up doubling my money, and I was very proud of myself because of that.

i think you can try to get much money here first, you can collect as many usd as you can, then you can sell it with rupee.

well..when u see it at rupee 42..then buy it! so just keep it till you wanna sell at a higher price..it won really do much ..unless u purchase a large amount of dollars.. say maybe 500 dollars,,
