When is the time to start buying altcoins again? Well, it depends on the price action of the specific alt. There are 3 phases of price action: Downtrend, accumulation, uptrend. Downtrend: You want to absolutely AVOID buying here. Most alts are in downtrends right now. Don't catch knives. Accumulation: Once price starts to settle, this is a sign of seller exhaustion. If price continuously respects a particular level (range low), you can bid this level and cut below (invalidation). Uptrend: Once structure shifts from bearish (downtrend) to bullish (uptrend) you can get back in on either a) a break of structure, or b) bullish continuation pullbacks. I'm personally following these guidelines for any altcoin purchase/spot trade over the coming months.
