There will be no alt season (similar to the whole 2017 year), only few months of pump and huge dump after that.
Why do we have to care about alt season as crypto investors? Without the alt season, if there are good waves for XEM, and investors are wisely to choose good entry points and determinantly exit at the right high price, they will be able to get profits from the market. It does not make sense if there are alt season within one year but one investor only loses capital from stupid investment decision.
In 2021 near the bottom of global crisis whole cryptomarketcap will do new dip toghether with weak stock markets (US is special case, capital in fear will park there and in dollar, after that in Gold - when this wave of optimism in Wallstreet will end, not in Crypto!).
If there are crisis, it is good for crypto.
