Let's give an example of you bought 100 BTC at 9000$ Price and the price went 9010$ in seconds then you sold, so your profit will be 1000$, may 500$ fees, but the another 500$ you made it profit in seconds!
Let's discuss at the point!
This proves that the more money you invest, the greater your chances of making a profit. I imagine what if a large investor bought 100 bitcoin at a price of $4,500 to $5,000 some time ago and sold it today. Really this is just a fantasy like flying without wings because we can only daydream.
I never had that much capital, in fact I had to sell most of my assets to own $ 10,000. We are small traders with $100 - $1000 capital, but we have at least a small profit. Imagining big profits will only help pump up enthusiasm and motivation to be able to produce something bigger.
