Germany transferred a total of 3,100 BTC this time

2,500 (B2C2 quantitative agency) + 400 (kraken) + 200 (market maker)

At the same time, from last night to just now, a total of 1,700 BTC was withdrawn from the exchange. I learned the art of war and withdrew 5,374 BTC from the exchange before.

Before, I sold 500-600 BTC every day without thinking, but now I start looking for market makers. It has become a game of selling 10,000 and buying 5,000, which directly maximizes the profit.
