I don't own even a bit of BTC....I can't be the only one right?

I got into crypto recently and I ain't a rich kid so I feel like investing in ETH(DCA),ADA,VET, MATIC and other alts would get me more profit compared to BTC.

BTC is too expensive for me. Is there anyone here who doesn't own BTC like me? Or am I alone?

I don't think I am doing a mistake as the highest amount I could put in crypto per month is only $50(third world country student)

Edit: sorry I said BTC is too expensive, what I meant to say was the gains in ETH, ADA ,MATIC and other alts is more(greater risk and greater gains) but thanks for all those who patiently explained a rookie like me about the wrong in that statement! You guys are the best of this community not those who are telling me I'm stupid and contributing nothing.

Edit 2: I can't start DCA ing BTC with my current money and I can't cut the alts out too cause I like those projects, I'll get job in 1 1/2 years and will start buying BTC for the long run. Thank you!

Edit3: when I say I have $50, it doesn't mean I'm from a well to do family, I save it by cutting down extra costs like not buying expensive clothes and not buying junk foods. It's awesome how much I could save up by cutting all those lol
