I think this alt season will begin very soon, before the end of this year, and will last about a month, since we have been waiting for it for a very long time, for 3 years. I have already prepared for this and purchased altcoins.
What if it didn't happen like you say? what will you do ? because all of those people are not gods who can know the future or tomorrow, if you say this alt season will start soon, before the end of this year, then you have stepped over God. As for the length of time in waiting, everyone experiences the same thing, so don't predict the future where the possibility is not yet possible.
