Of course, if he makes only $3 profit, that probably won't even cover the fees for buying and selling bitcoins, but he will still make a profit. And learning to trade from scratch with $30 will most likely result in him losing the entire $30 altogether. I can quite possible to advise him to buy bitcoins, especially in a downturn, but I personally would not dare to advise anyone to start trading, the risk is too high.
Yeah, trading is expensive, and most people will end up losing money, plus the fees are constantly there.
With $30 OP should focus on learning about Bitcoin, lightning, etc, it's a great opportunity to move Bitcoin around. At the end of the day it's the same if OP was moving millions, so better to learn with less money as mistakes would cost almost nothing.
I wouldn't focus on trading, just on learning the tools of Bitcoin.
I agree that spending $30 on bitcoin is a waste because it isn't at all lucrative. This is something I've seen when I first start investing. I consistently invest $5 to $10dollars, and I always end up losing money. When I think about it, I giggle lol.
In my opinios(as of right now), you shouldn't invest in bitcoin if you have between $30 and $50 to invest because it is essentially unprofitable and the investment is long-term. Instead, you should learn more about cryptocurrencies and how the investments work so that when you have more money to ivest, you won't be concerned because you have knowledge that anyone can acquire.
