We knows that the crypto currency investment can give us lot of profits even in short time but this is very new there are lot of invesments like real estate,gold,mutual funds silent partner in businesses and lot more but what you think which has highest ROI in short term other than crypto invesments.
My opinion is that real estate can be that one,since my grandfather used to be like buying and selling the lands and made tons of money in his life time but I didn't do that such kind of traditional invetment.
Well, also realize that crypto can also lose a lot of money quickly, and is very volatile compared to other markets.
One cool financial dude to listen to is named Dave Ramsey. He talks about investing, saving, etc. Gives talks, makes videos, I think you'd like him.
I had the privilege of talking and listening to Nick Halik, who's a very wealthy investor and businessman. This was a while back, so I'm not sure if things have changed, but some of the things he was talking about were shipping container rentals, and owning your own ATMs, both had good ROIs - obviously depending on the company and on your own personal knowledge and dealing.
I've also heard that certain life insurance packages can be a good investment with decent ROI, could be something to look into.
If you have larger capital, things like real estate, oil wells, diamonds (be careful with that one), etc. can all be considered, and all require some higher levels of knowledge.
Precious metals, of course, are highly liquid and are generally seen as being long term investments, and good in case the crap hits the fan.
One of the most important financial investments is your own business, with which (if successful) you can use your profits for further investments. Josh Tolley (JoshTolley.com) is a great guy to look up and a top business coach (also a radio host). Written at least two books, one called Evangelpreneur, and the Quit Your Job Or Die. He's also got his Purple Monkey Institute, and his Purple Monkey Garage.
Have a great day!
