Never underestimate the power of compounding interest.
If you're thinking that investing $50 a month is little, chances are you did not work out the math.
$50 contribution per month in 8% interest per year is 155k in 40 years.
$100 contribution per month in 8% interest per year is 310k in 40 years.
Note that the above target is not hard to achieve at all. Now, imagine if you put in more per month.
In addition, Bitcoin & Friends has proven that the average gain per year is way more than 8%.
If you also happen to be staking, you'll be compounding the compounded balance per year, which is perfect.
"Investing with little money" can eventually lead to "massive gains" due to the power of compounding interest.
Do not ignore investing just because you think that the amount is very little.
Start early, so that you can enjoy life early.
