Hearing testimonies from different sources, I can only conclude that "You don’t need to be rich to invest, but you need to invest to be rich." Riches aside, investment can increase your financial freedom, but the problem with most people is procrastination, they want this BIG capital to invest, but it is not like that.
From real estate, stocks to crypto, we have seen people buying their assets that were deem worthless, but suddenly became their source of wealth. I remember someone who couldn't afford a land at the city center but wanted to invest. He bought it at a rural area where he could buy over 1 acre. Not long after, the government decided to build a Federal university in that locality. Right now, a plot of land there can buy a plot of land in the city center that he couldn't afford, that is the power of investing.
It mustn't be convenient, it mustn't be in thousands of dollars, a little that is being consistent about and carefully thought through could make that wealth. Start investing today.
There are several assets one can invest in to create recurrent profits for himself although some requires some big capital to have a reasonable ROI after a period of time but there are those that doesn't really demands much of a huge capital to start with. The problem with some persons is that they want to start out big and they then start procrastinating and eventually never had to do anything and time get past them to have taken up some opportunities when it availed itself. Take bitcoin for example, there were people who saw it in it's nursery stage but procrastinated, today they are regretting.
