Start small: Start with a small capital, say $100.
Currency Selection: Choose a currency that is not volatile.
Leverage: Use leverage no more than x10.
Leverage Limits: Make sure you do not exceed leverage of more than 50% of your capital (e.g., with $100 in your portfolio, your leverage should not exceed $150 = $15 x 10).
Avoid trading at the same price: Never buy or sell any currency at a price equal to your entire margin.
Split Margin: Divide your margin into 4 parts ($15/4 = $3.8), meaning you will open a long or short position with $3.8 x 10 = $38 USDT.
DCA Strategy: If you open a long position and the currency drops 5-10%, buy it back at $3.8 x 10 (this is called Dollar Cost Averaging, or DCA), so your entry point is now lower. The same goes for a short position if the currency rises 5-10%. Your position will now be $76 USDT and you will have $100 as your balance.
If the coin crosses its breakeven point with a profit, close it. If it drops another 5-10% or more, DCA again. (Never DCA for a 1-2% drop).
Charts: Select duration such as 1 hour, 4 hours, 1 day). Analyze the charts to see how the currency is behaving.
RSI Indicator: Since you are a beginner, use the RSI indicator for duration (1H, 4H, 1D, etc.). If the RSI score is below 20, it means it is oversold and may go up a bit, so it is safe for long term. If the RSI score is above 90, it means it is overbought, so it is safe to go short.
Stop-Loss: Never trade without SL; It is a lifesaver when a crash occurs.
Patience is the key. Stay up to date with the market. Enter and exit trades on time and never trade as a consecutive player. Once you have a profit, take it easy and wait for the next safe entry. If you have a loss, take it easy and don't rush to recover; you may end up losing more. Wait for a safe entry.
