Many alts, big and small have started higher timeframe reversals from multi-month (or year) downtrends.
Generally, whenever altcoins move, especially a few years into a cycle, the moves are violent.
When zooming out they might seem like up only but there's often several quick 20%+ flushes within these runs that do multiples over several weeks/months.
That's when you should strike and get the buys in on the things you want. When longs are being flushed, is generally the best risk/reward for you to enter.
