-In my opinion, crypto could be ATH by the end of this year so to build a portfolio at this time is still very feasible if you want.
-A bear market can happen like 2018 after ATH will take effect if this year Crypto experiences ATH, the possibility of a correction market can occur next year.
Slightly disagree with what you said because so far I have never seen a big correction like in 2018, because this year it has experienced several corrections, but it always recovers faster and it didn't exist in 2018 where the correction took a very long time, so every year the conditions are always different, both corrections and price increases.
