Being able to earn after reading books or doing courses is a theoretical thing in my opinion, and it doesn't really happen with everyone, especially in a third-world country as I believe OP is from a third-world country. Though I encourage people to learn skills as they can be useful, I think investing any extra money you have in Bitcoin will do you no harm in the long run.
Even if he only gets a small amount back after the price reaches significantly high, he will still be the happiest since his investment at least worked, I think he knows that he won't become a millionaire with only a $64 investment.
He has access to internet and knows english. Thats enough to earn online no matter where he leaves. The fact that he is from third-world country is even better in this scenario because of much lower cost of living and foreign income.
There is nothing bad with his 64$ investment. The problem starts when he check his portoflio 14 times a day to check if he is 1$ on profit or 1$ on loss (according to binance, its
average user check app 14 times a day).
The amount of time lost in this way combined with stress may not be worth the few dollars in profit, especially since bitcoin is already a bit too big to do 100x in a year.
