To begin with, use intelligent copy trading to take profits and avoid adjusting the multiplier randomly. BCH high frequency, AI quantitative trading, not grid, not martingale, not hedging; use the appropriate opening method at the appropriate time. It is recommended to have at least 220u (Ether is getting more expensive, check how much is needed to open a position around 200). Follow the copy trading based on multiples of 220 to maximize economic benefits, otherwise there is a risk of failing to open positions. It is advisable to follow up after a return. Be aware that if there is a black swan without a pullback, it may lead to liquidation. Investing carries risks; it may be wise to observe for a few days before deciding whether to follow. Do not operate on your own; leave everything to AI.
