$BTC Sold the still falling ETH at around 3 AM, then went all in on BTC with over 30 times leverage. Woke up at 10 AM and got liquidated immediately. Learned my lesson; if I had held onto ETH, I could have made over $100 by morning. A novice quickly learns to be cautious. One must have respect for the market and avoid high leverage. Seeking guidance from the experts, how should I manage small investments for the long term?
