The fluctuations of btc/eth are now determined by the Americans.
How can we determine through simple signals whether the Americans are increasing their positions to buy or sell?

Since the most traded mainstream trading pair in the crypto market is usdt, but the Americans deposit and withdraw using usdc.

Therefore, through the slight fluctuations in the price of usdc,
if the Americans are increasing their positions or plotting to buy in a stealthy manner, it will manifest as selling usdc to exchange for usdt, causing the price of usdc to drop, and btc/eth is very likely to rise.

If usdc rises, it indicates that the Americans are selling btc/eth to obtain a large amount of usdt, and then selling usdt to buy usdc, which manifests as an increase in the price of usdc. In this case, it is very likely that the Americans are brewing a bearish scenario or are in the process of selling btc/eth on a large scale.
