Investing in altcoin at the moment is not bad, in fact if the price of BTC continues to fall, it is much more attractive to continue buying Altcoins, because that is the logic that governs the market, of course everything is based on the fact that if you buy it right now it will not It should be sold unless it is in eventual profit.
For me the best investment will always be BTC, but altcoins represent great power if they are bought very cheap and sold very expensive, and those are the opportunities that few see.
Low altcoin prices should not make us greedy to invest more into altcoins. The altcoins can even go further down if the bitcoin crashes. Some altcoins may never reach to the all time highs again. Most altcoins pump on the basis of hype , so we should be careful in building big positions in alts. I'll prefer to invest majority of your funds in to bitcoins.
