$BTC $ETH
If you only have a few hundred dollars, don't think about financial freedom. Even entering the game requires some threshold; going to gamble with a few hundred bucks is like street gambling, and it's all a scam.
Charlie Munger has also mentioned a similar concept: the first $100,000 is the hardest, but no matter what twisted saving methods you use, you need to find a way to accumulate $100,000 before talking about investments.
$100,000, roughly 70 units; even if it's a bit less, there should at least be 50 units. Bitcoin has a high return rate, and even if you calculate a bit lower, there should be at least 10 or 20 units. Thinking you can achieve financial freedom with just a few hundred or thousand dollars is a bit unrealistic.
Every round of getting rich overnight with 100x leverage contracts has a few lucky ones, like Liangxi, but their luck is built on the backs of thousands of bankrupt victims, and Liangzi's outcome is well known.
If your principal is small, focus on working more, avoid debts, complete the original capital accumulation, and then come back to invest or speculate. Buy high-certainty items, follow long-term trends, and gradually become wealthy; that is the right path.
This path won't make you rich overnight
But it can save you from irreversible ruin.
