Do you think investing money online is a good idea or just another waste of time and money?

It's not a question of HOW you invest it. It's WHAT you invest in that matter.

If at a good brokerage like scottrade, merrill edge, etc and you buy stocks that go up, then yes it seems like a good idea.

If you make informed decisions and approach your penny stock investments with the same thoroughness that you’d use in your other investments, you too can unlock a whole lot of profit potential. Learn here https://tr.im/learnpennystock

It’s absolutely true that penny stock investors can make very quick gains. Synutra International, Inc. (NASDAQ: SYUT) is a great example of a penny stock. This dairy-based, nutritional-products company has jumped from a little Bulletin Board operation to a billion dollar corporation. The company finally graduated from Over-the-Counter status to the NASDAQ Stock Market bringing with it 113% gains in less than two months.

This happens all the time and it’s how some of the best investors in the world became the richest investors in the world. Buying some shares for pennies on the dollar and selling at $10 or $20 is possibly the fastest way from being a hobby investor to a super investor

It does have some drawbacks, the Internet makes investing easier, but making good investments is as hard as ever. Even if the investment websites you use have tight security, hackers have multiple ways to steal your password or trick you into handing it over. The Securities and Exchange Commission notes that a common problem for online investors is that they place market orders for fast-moving stocks.

investing money online is probably not a good thing, however, if you are referring to establishing a discount brokerage account and doing your trading online, that is fine

a good idea? Is there another way to do it? I've been trading for 29 years, and I can tell you investing money online is the best thing since sliced bread.

How would you know whether it is a Scam or not?

It depends on what you are investing in.
