Probably, the best time for people to invest in the crypto market, so buying and selling altcoins depends heavily on the price of Bitcoin. enter the crypto market and make a decision to sell or keep it.
Selling and buying actually depends on the needs of each individual, because everyone will also have different needs, so when is actually the right time? When the thing that is needed is not really needed I think HODL is a pretty good thing, because seeing from the side of the positive trend that continues to occur in BTC, it is not impossible that bitcoin movement will experience a new ATH.
Currently Bitcoin has broken the New ATH from 2017 when it was 19.8K $. Judging the right time, maybe this really depends on each individual, but everyone who has a long-term investment has a target price. And the current time is indeed the right time because Bitcoin is still in a Bull trend. For altcoins, there is still potential to create a new ATH. although at this time if we count there are many that have created an increase of hundreds of % on a 1 year time scale.
