The pair of $BTC (Coin Pair) is like a married couple, the only difference is that they do not give each other divorce, but dance according to the market's mood. One day BTC goes up, the next day it comes down, as if a couple is having an argument! Sometimes romancing with ETH, sometimes joking with USDT. But whatever happens, the poor little coins just remain spectators. The BTC pair is the market's "drama serial", which changes its episode every day. The poor investors hold their hearts and say every day: "Hey brother, what has happened now?"
