Simply put - investing means putting money into an asset, with the expectation that over time the value of that asset will increase and, you as the investor, will earn on that increase. From there, you can either sell it for more than you paid or hold onto it and gamble on the increase in value.
Investors use the term "asset" to refer to anything of worth or a resource that may help them generate money in the long or short term. The value of assets can go up or down and often both…..we know, it’s hard to keep up!
