Which coins should we focus on from a technological perspective now?

1. First, confirm the level and rhythm of the current pullback. Usually, the boundary is defined by the current cycle's MA20 moving average line; a significant drop below this is considered a formal pullback at the current level. From this perspective, most altcoins’ movements can be seen as confirming a daily pullback.

2. Classification of the downward rhythm. Coins like $ACT and $PNUT, which have a very smooth downward rhythm, are clearly not in the bottom-buying expectation. If a right-side price structure appears in the observation range before the drop, such as $virtual, and the left-side support point has shown performance, then the rebound at the key position will be relatively quick.

3. Most importantly, predict the movement of Bitcoin. As long as Bitcoin does not confirm a rebound, all altcoins will be suppressed. According to the previous expectation of Bitcoin's daily pullback, as long as there is a recovery action confirming the rebound, one can confidently bottom-buy some altcoins.

4. Actions after bottom-buying. Once Bitcoin confirms a daily-level pullback, the likelihood of another daily-level increase in the short term is relatively low, so the expectation is a wave of 1-4 hour level rebound.
