Do with the whales, buy low and sell high, there is no mistake, the problem is that we will have fluctuations and we need to be patient to wait and cautious in our choices.

Don't do this, you'll go broke, whales manipulate the market. Every day they trade at 9am, 12pm, 3pm, 6pm, 9pm, and the most dangerous are the Asian ones at midnight and 3am.
