I can't give you a smart way to make money from crypto trading, but I can give you things you shouldn't do (or at least need to reconsider) based on what I did before, so you can minimize or prevent potential losses. I've been in crypto for 10 years, and sometimes I made the same mistakes because I'm too greedy. I want more money in a short time.
Here are the mistakes I made...
1. Selling my BTC just because of bad news and a bad chart I saw, believing BTC would go down further, and then thinking I would catch it again at the bottom. Most of the time, I didn't actually buy it back at a lower price because I was still not confident whether the current price at that time was already the bottom or not. I just didn't have the guts as well. Another reason is that once you sell it, you have cash, and you'll start thinking about what you can do with that cash. You also don't know if you'll need the money urgently in the future, so you can't buy back the BTC you sold before. Once you sell and the cash is gone, it might make you lose some of your motivation.
2. Trying futures trading. Based on the stats I read on the internet, roughly 90% of traders lose money in the market (5% loss, 5% breakeven). If you don't have the skills in trading, it will end up just like gambling. And as with gambling, chasing losses could happen in your trading activities. Don't think about joining channels (paid/free) in the hope of making money by using their signals. I did that and lost money. They are just traders, not the owners of the market. Even big fund managers or traders only make a small percentage of profit annually in the long term.
3. Using AI and relying on AI decisions. Been there, done that. I built an AI agent using OpenClaw to automatically trade futures on a CEX. AI can't predict the market well by only relying on algorithms you build based on technical analysis theories. I've tried backtesting many strategies, and the best I could get was roughly 400% in 8 years. I used BTC price datasets from Binance from 2018 to 2026 [2] as the data for the backtesting. So, don't blindly believe social media posts saying, "This AI agent made xxx from trading...". Search for the truth first. It's possible, but the way it makes a profit is usually not from the trading decisions it makes, but could be from exploiting systems, speed, price differences, etc.
4. There are actually many more, I just can't remember them for now. Will edit this post later if I remember
