Cannot break through! Go short! Short 33! Fall for me

I don't understand! Can anyone help me solve this puzzle? Why is the price of buying coins in the trading area 6.9 and selling coins 6.95? What's the logic?
That means I buy 100 coins for 690 and then I can sell them for 695! It's unscientific! Can anyone help me solve this puzzle?

I'm curious and want to ask a question! A bunch of people who seem to be big shots are talking about support levels, and what will happen if they break through. On the other hand, they are also talking about Duzhuang controlling the market and so on! These people have said all the words. But I feel that this should be a conflict? Since they can do whatever they want, what does it have to do with the title? I'm a newbie and I'm just curious

The posts in the square are all the same! Hello everyone, my name is Hindsight! I warned you a few days ago that today's situation will happen. If you don't believe it, look, it's exactly the same as what I said! Of course I deleted all the posts that said different things! You see, everyone who is alone with me eats meat! How can playing with coins be as stable as cutting leeks! Come and join my group

Please share it with more normal people! Whether it’s a diary, how much money you’ve lost, or how much you’ve made, it’s all posted on the picture above. Let’s communicate with each other. How interesting! Now it’s all posts about cutting leeks, prediction posts! I post a few posts every day, delete them if my predictions are wrong, keep them if they are right, and then start pretending, it’s disgusting! Now I don’t have any intention of learning when I go here! Just looking for a clown to watch a joke!
