6. How to calculate the purchase price of RMB 5000 for us $36000 bitcoin
(5000 x a) / 36000 = 0.0218

A is the ratio of RMB to us dollar at that time (that is, the exchange rate of RMB to us dollar at that time)
A = 0.15696
the exchange rate of RMB to us dollar on January 20, 2021 is 0.154304

7. I think okex is very good. It supports buying and selling bitcoin in RMB. If the commission rate is low and the transaction is frequent, it can save a lot of costs. At present, it is the world's largest bitcoin trading platform, and it's more reassuring.

9. Take the pulley as a whole, and the force on each rope is the same. For example, when a pulley block moves, the driven pulley starts winding. At this time, the tension of the ceiling on the rope is the tension of the rope on the fixed pulley. And this force is equal to the sum of the fixed pulley weight and the pulling force of two people. That is G + 2F. If the winding starts from the fixed pulley, it is G + 3F. Remember: the upward force is equal to the downward force
if it is a horizontal pulley block, if the friction is ignored, the force to the left is equal to the force to the right
this kind of ideal problem, that is, the problem of friction is ignored, so it is most appropriate to use force analysis to solve the problem
it has something to do with people's pulling force.
