For one, understand you cannot win every trade but strive to won't 40%+ when starting. Understand stop losses. If you trade on exchanges with just limit and market move to swing trading. Ideally you want to limit each trade to under 5% of your day trade portion. Understand buy and sell ladders. Set price targets, take profits sooner rather than later. Don't trade low volume coins, stick to higher volume at least 200+ btc. Don't rely solely on one indicator or candlesticks alone. RSI and MACD are useful for entry exits. Never try to trade multiple coins at once.
