I just use doge mostly. (Much regret because I used doge there as trash coin before the boom, lol. Woopsie. What was like $20 in my statistics is now $4000). Lesson learned, sort of.
It is really a trash coin, no one knew that the price of doge would skyrocket, it's just illogical, people buy trash because one man says that trash is good. It's not your fault, at least you are not a supporter of trash blindly like others. Doge is a good lesson to learn and understand the behavior of people.
I do find using USDT makes me more aware of how much I am spending. It's a little difficult sometimes to know just how much I'm blowing because I can't do the conversion in my head easily.
You can immediately convert the coins into USD and save that in your excel file. In one column write the amount of bitcoin and on another one - current value of those coins.
I think Woflbet will soon fix all the issues that people have right now regarding to fees.
