It's likely that it has ended already its surge but there could be recovery still for it.
And adding the fact that when the price of bitcoin starts to drop it drags all altcoins away, it's definitely not a good time to buy that altcoin.
Yeah, the alts have been hit hard whenever bitcoin drops a lot. It's up to them if they'll buy shiba while the market is plunging. The whole market's last hope, bitcoin has dropped a lot and they've been affected that much so whether they think it's a good buy or not, they should think of it first many times before doing so. No one knows what's with it in the market at the end of this year but a year has passed already when the bull market has started with the same period.
