As mentioned in the morning, it has been a volatile upward trend today, but throughout the day, except for Bitcoin (BTC) which is relatively strong, the mainstream and altcoin heat has noticeably decreased, indicating weak sustainability. BTC has basically reached its previous high position, so it's better to be cautious and not bet on a breakout, especially after suffering significant losses in the big A market a few days ago. Currently, I have manually reduced my position, and my account is balanced with yesterday. Moving forward, I will only open light positions in BTC and ETH. Based on the market, I will consider adding new coins later.
