Maybe, but that's not how I do it. I just buy stuff when I need it regardless of price and save all my surplus in BTC regardless of price. I don't know how to time these things . 

 Nah, I understand and agree. Just checking my knowledge of the fees that are price contingent. Although I guess other fees are contingent on workload and timing 

 Most of the time I buy stuff with lightning so fees are not a factor
