Alts turned bearish on the monthly chart

The only reason why i havent sold my alts is that BTC is still in a bull trend on the monthly. If we close under the 21 EMA on the weekly BTC chart, im deffinetly dumping my alts, because things can get ugly very fast. So for now the chart on BTC is still bullish, however there is a divergence with the charts on the alts which are bearish. Now the picture is not clear anymore in my oppinion. There is two ways to look at it. Eather the alts are leading the way on the downside or this is a buying opportunity if we continue the uptrend on BTC and alts will have one of those 3 4 month rallies in which they 3x - 5x.
