Quite frankly, the whole market is in that "severe crash" as you know, Bitcoins price action affects all other cryptocurrency prices hence the dip you see with all other crypto prices.
Most people can't enjoy the "severe crash" that's happening in the market today and that's perfectly normal because they probably bought at a high price.
But I can still be patient with that because I only make purchases when the decline occurs or when the price is low and it won't be a problem if I buy I have to hold it for a long time.
Bitcoin thus far has dropped -71% from its ATH and could still dip more and yes some Alts have had a worse dip from ATH but I believe that a few Alts also have proven themselves and can go through the bear season as they have done before.
Bitcoin will still create ATH even though it has dropped -71% of its ATH so far, because the opportunity for Bitcoin to create new ATH is still very wide open and yes, don't hesitate to continue to own Bitcoin and hold it until you find a commensurate profit. Likewise, altcoins that can still survive this period of decline because of those altcoins that are able to survive, will definitely be able to pass this bear season very well.
