Today have another coins hype with PEPE coin but not really recommended investing right now on both coins because have reached higher price, I don't recommended without risk when investing in shit coins but have worth and faster profit returning than you invest in Bitcoin with amount $30, its not mistake starting invest in Bitcoin with 30$ but need more patience waiting more than longer time to get profit than investing in shit coins.
You are not wrong because everyone has different views and ways of investing, you don't need to be like anyone else, just be yourself. I also don't have a problem with someone getting started with bitcoin with as little as $30 because everyone's income and economic conditions are different.
But if it were me, I wouldn't invest, and instead, I would start learning everything about the market and try to make more money before investing. Or another solution, I'll invest in shitcoins, the meme craze is back, and I'll try my luck, and of course, I'm willing to lose that $30.
