Recently, there will be similar altcoins like #NMR and #PYTH that experience short-term surges and double in value. If you're already in, the approach is simple: when it rises to a key resistance level, take some profits first and adjust your stop-loss line upwards, then patiently leave the remaining position to the market. If you want to get in at this time, it's not impossible, but you must use the EMA moving average as your stop-loss line and calculate your position in advance. For example, let's say your principal is $10,000, and you control the risk per trade at 2% (i.e., $200). The current price of the surging X coin = $50, and the EMA moving average is at $48.5, giving a price difference of exactly 3% (0.03 × 50). So, the number of coins to open = 10,000 × 0.02 ÷ (50 × 0.03) = 200 ÷ 1.5 ≈ 133 X coins This means you can buy a maximum of 133 X coins, with a position value of about $6,666, accounting for 66.7% of your total principal. This way, even if the price drops below the moving average and hits the stop-loss at 3%, your loss will not exceed $200. Lastly, and most importantly, the above risk is a position method; when you open a position, you know how much you might lose, but whether X coin goes up or not depends on whether the market maker of X coin is generous or not~
