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!
One who has the money to invest in Bitcoin $900 000 will not get rich by profiting only $500, so I don’t see how anyone can get rich this way and why they would sell at all if price is change for only $10. But if someone invested $900k and bought 100 BTC, then selling at $10k would make a very nice profit of $100 000 which already makes some sense.
The bitcoinBTC that the most of day... not outting of 9000$ will go 6k in the moment of i buy?
This will be called really cheatting if that happend!
It’s a free market, supply and demand or call it whatever you want. There is always a risk with investing in something extremely volatile such as Bitcoin, but similar things can happen to you if you invest in stocks. You are investing in a stock today, and tomorrow some catastrophic news appears that practically destroys the company overnight and the shares fall sharply.
While it may not be a real comparison, take the example of
Apple which in 2018 became a company worth $1 trillion, but shortly thereafter the value of the company was almost halved. Those who invested in those stocks at the time lost money unless they waited for the company to recover and reach the same or higher value again.
