We have seen a lot of price change in 2021 for most of the altcoins. The price of altcoins will be changing more at the beginning of 2022. It is still possible to take profit from altcoins if we buy at this time. Otherwise it will no be possible to but at a lower price what we are seeing at this current market.
It could be, if the trend still growing up, Bitcoin and Altcoins will grow together and we're goin to another moon before end of the year. Nowadays, it time to pickup the strong project with a strong fundamental as a background.
As there is no right or wrong time to invest when it comes to btc and alts, just pick and study promising projects and evaluate if they are worth buying. As most will be crappy after few months in trading, it is better to be think hard where to put your funds rather than regret later on because you were screwed by scammers.
