Last month was something else because Bitcoin actually increased to a new ATH. However, the market is not stable yet, as it continues to dip and increase within few hours. However I think one shouldn't bother at all because it will still increase no matter what. No matter how altcoins adds value, it can not be same as Bitcoin. Investing into altcoins for short term might not be as terrible as investing into it for long term, investing into altcoins for long term is not different from gamble.
The market not be suitable as we want or expected it to be since the market did not continue with it all time trends momentum or sustaining a balance benchmark in terms of price stability, but that been said, we will never see the market going dipper than 90k benchmark before the next all time record will hit the market again.
Between when that will happen, we will likely see altcoins riding along with the new wave of market bull, unlike what happened in the last month when Bitcoin actually recorded a new all time high.
