What do you think is the perfect time to build a new portfolio?
It must be during the bearish market and the thing that you must try to do that to buy in the various entry price. You should not peg with one entry price and this will be making your portfolios goes down once the market was making the price of your token goes even deeper than it.
Bear market cycle can take 2-3years some times is it wise to build portfolio right after bear market takes over? Judging from past years coins and tokens loses 95% of their value but not in an instant it was a gradual process, I think same thing will happen
None knows how long the bearish trend will be happening but as long as you have reserved funds and then you can try to take various entry price as you have backup once the price goes down. Can you predict when the market recover again accurately? this must be your big question.
