Spend coins today or wait till Saturday?

My TT recently got a lot of really expensive cards, including a bunch of LTDs. I haven’t bought any of them except Alshon Jeffery because as a rule of thumb I don’t buy cards for more than 400k. I currently have a stack of 4.6m coins and im a sms player, basically I’ll just buy a $20 featured deal here or there if it seems worth the money. 

I’m willing to spend a good chunk of my coin stack to get players right now instead of waiting weeks for reduxes and allat, cause TBH I don’t know how much I’m even going to be playing ultimate team in 2024 anyway. 

To get my coins worth should I drop a lot of coins today or wait until Saturday?
