Good observations and completely incorrect analysis. Indeed, altcoins have moved against BTC, and there are many shorts. But this is precisely a signal that BTC will reverse, not that it will go lower.

Judging by yesterday's market and today's market, we are seeing an extremely rare situation when Bitcoin is in a steady downward trend (the descending red line in the figure), but at the same time most altcoins have gone up.

This only means that when Bitcoin reverses, altcoins can quite sharply go into the recovery phase.

At the same time, the number of short traders on the market is currently at its highest level since November 4, which means that there will probably be another attempt to push Bitcoin lower. On the other hand, the American stock market is only open until lunch today and tomorrow is the weekend, so there is little time left for major players to push the market down. So I think that when short traders are liquidated, the market will make a good jump up again
