Coin preparation help

Somewhat new to MUT. Played the last 2 years. I’m trying to learn when I should sell team to prepare for new drops and minimize on the coins lost. Should I go ahead and get ready to sell my zero chill players to gear up for next drop or does the community think they will hold value for a while longer?

I’ve seen it is usually  best to sell right before the next season because of updated odds. However, I never do that because I feel like it’s a gamble I’m not willing to lose.
