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!
Discuss what?I can't buy 100BTC even if I sell my house and my car.

If you buy 100BTC you will spend 900,000 USD and your profit will be less than 1000 USD.
Your profit will be less than 1% of your investment,so why should you care about such small profit.
If I could spend 900K USD on something,I would definitely buy some super fancy car and get some hot girls as my girlfriends.I wouldn't care about Bitcoin at all.
