Last week, BTC bounced from $76,046 to $79,890, climbing back nearly $3,844. Now the price has returned to $76,756, with about 82% of the rebound given back. Looking at the 4-hour chart on AiCoin, BTC has been forming lower highs below $80,000, and the price is once again approaching last week's low. In just one week, BTC first lost the $80,000 level, then quickly rebounded, and finally returned to near the starting point. This nearly $4,000 rebound has almost completed a full round trip.
