hey bro, can we buy gold on credit card?

 Yes, you can. But there's a charge of 3% so unless gold price has plummeted, I would advise against it. But then again, if you're buying gold as long-term investment, it's worth it. 

 Invest in Index funds, such as SP 500.  I don't recommend to buy individual stocks unless you can spend a lot of time tracking those stocks.

 Appreciate your response, TND. How do I go about it, though? What tools do I use? Invest my money via banks or is it one of those DIY thing? How about the rate of return? I looked into the stock market and the sector over the weekend and that seems like a no-go to me for the reason already mentioned by you. I'd much rather invest my money into gold than risking it (albeit I've been really tempted to put in cheeky offers to buy some FB stocks). 

Index funds can be invested in via a standard brokerage account such as scottrade, etrade, zecco being the cheapest, i think....etc. Or you can use your 401k, if you have one. 

Few things to know:

ETFs are cheaper than index funds, in terms of fees
If you plan on trading often, fees can become substantial 
In terms of rate of return, it depends on the fund that you're planning on investing in

IMO, the time to invest in Gold has passed, since the prices have increased within the past year, and you really wouldn't be getting the biggest bang for the buck for the short term. But Gold isn't the only precious metal that you can invest in, there are other commodities that you can invest in such as oil (in the simplest of terms), but that's where it starts to get complex. Check Yahoo finance for GLD, and analyze its one year trend.

In the end, it all comes down to what suits you best in terms of risk, I know I'm not being of much help but there's no escaping your due diligence. The one thing I would suggest against is investing in something that you don't understand (per warren b). 

Good luck!

how much gold can we take from USA to Nepal? And do we need to pay tax in Nepal?

Appreciate your response, foxconn. Will look into it later tonight. 

Jhapaliketo, what sort of gold are you talking abt? Gold coins/bars or jewellery?
