The brother who has been copying trades for a month has already doubled his investment, and the one copying for half a month is also close to doubling. Doubling in a month means a 2x return, and 30 times is 2*2*2*2*2=32 times. In five months, you can achieve a 32x return! Compound interest is fast, and the later it gets, the faster it accelerates! Turning 300 USD into 10,000 USD is at most a five-month process! Those copying trades need patience; even when there's no market movement, it's normal for me to hold a single position for a week!
