Making money from money is possible by buying some bitcoins and selling them after its price increases which is risky too.
Yes that's one way of making money from your money. And if you got a lot of it those bought bitcoins can be used also for investing into a casino and in that way you can also have a chance of making money from your own money or investment. Actually there are a lot of ways to earn from it and it really depends on your satisfaction.
Unfortunately a lot of money can be earned only on risky transactions. This must be very well versed in the subject and have access to insider information. It is very difficult so I don't do investments. Remember 2008year.
