Just now, the big coin went up to 684 with a big positive column, but it didn't reach 685, otherwise I would have stopped profit. Now I can close all positions. Then I plan to buy more near 673-676. The US stock market has risen sharply. The data from the University of Michigan is also bullish for the crypto market and US stocks. If the momentum does not decrease, it may touch 7 tonight. It should not be a problem to stand firm at 69. It depends on whether it can reach this point. It is best to reach it. It doesn't matter if it can't reach it.
