There is no doubt that at this time we must invest to improve the future, do not focus on active income because when we cannot work then we will regret, investment does not need to wait for us to be rich or have a lot of money, we can start with a small value for example $ 100 Then we add according to our abilities.
It seems you are not talking about investing, but talking about how to save for the future. Because investment basically always requires capital, even if it's a little, especially if the investment is in cryptocurrency which clearly cannot be done without initial capital. So right now you are explaining about ways to save that might be brought into investment by buying something of value and of interest to many people.
And good investment today is Cryptocurrencies because of the opportunity to continue to increase.
As I said above, investing in cryptocurrencies always requires initial capital to run, because that's the way it should be. And one thing you need to remember is that every investment has a different level of risk, moreover investing in cryptocurrencies is basically very volatile and unstable with frequent declines and increases in the market.
