One of the best know says of Warren Buffet is "It is not about timing the market, it is about time in the market". What he means that if you let the interest compound over a long period, the results can be amazing.
Independently of the style of investment (crypto, fixed income, variable rent, high yield, ...), it is good to take a look about what compounding can do for you. Please, note that you would need to subtract inflation and that can be big in some countries if you only invest locally.
These are very simple simulations that shows you how far can your saving and investing go. In each one you put an initial amount on an investment and then you add a bit more each year.
For each case, you get the final amount on money you get depending on the average yield that your investment gives you (this not mathematically accurate, but is good enough. For example, the SP500 index in the past usually yields 6% and is considered a quite safe investment. I have calculated for 6%, 12% and 18%. I call this, the boring 6%, the "nice 12%" and the "the gods love me much 18%" average yield a year.
This will give you the graphs and results for 17 years. Why 17? No particular reason
SIMULATION 1: Initial savings 5000, and you won't add anything else.
As you can see, a final capital of 13.000 is perfectly achievable with a 6% yield, while you can dream of 83.000. This is not bitcoin remember
SIMULATION 2: Initial savings 1000, and 1000 more a year.
Better results overall, with a basic of 31000 and a dreamy 104 if you catch a great decade of yields.
SIMULATION 3: Initial savings 5000, and 1000 more a year.
Better results overall, with a basic of 42,000 and a dreamy 170,000, this looks like a great option.
Notice that this is not USD specific, so 170,000 may not be "dreamy" in your currency. However, if you think of it, it should not be difficult for the average joe to save 100 dollar or euros or pounds a month in OCDE countries, and the effects on retirement can be noticeable. See a
previous post on that here.
