Some friends have no feeling for event contracts, let me calculate it for you, pay attention.

2 to the power of 10 equals 1024

The reward for each correct guess is 0.8, which is 80%

If you add up all the compounding each time, see what it comes to.

What you need to do is this day, this week, or even this month, you must get it right 100% this time

Then get it right 10 times in a row.
