The last All time high was 60k USD for bitcoin and that time altcoins were riding pretty high. If the holders of altcoins have been so foolish to not sell even partial fractions of their holdings at that high then nobody can help them. Currently the market is bearish to bullish so I dont expect the altcoins to move up again anytime soon unless another crazy celeb goes out there and starts promoting.
The last all-time-high was approximately $64000, it is higher than $60000, the altcoins were at their peak at the time, before the bear market set and began. The market is bullish recently when El Salvador accepted bitcoin as a legal tender and also we hem Elon Musk said Tesla will start accepting bitcoin again, but I still see the recent bull market not going to last and another bear market may start, it is clear how altcoins are decreasing almost twice than bitcoin while the whole market iis bearish. If the another bear market set, it will be a big blow on the altcoins.
