and in my opinion it's better if you use $ 300 to invest in each altcoin and then hold it until 2025,
I'm sure you can get multiple results if you do.
And the advice to buy altcoins looks very doubtful. Do you know how many altcoins there are, which of them should be bought first? Obviously, some of the altcoins will not even survive until 2025, some will turn out to be a scam, this happens all the time. For an inexperienced person, Bitcoin remains the best option, but for a good result, you need to increase the amount of investment, because $ 30 per month is very little.
