I'm in the US. I started trading crypto for the first time this year. It's difficult wrapping my head around what to do with taxes given I've made hundreds of trades. One thing that's come to my attention is that it seems the complexity of taxes will increase if I hold a coin from year to year (with regards to gains and losses).

So my question here is - at least for this initial year where I did not properly separate my investment coins and my trading coins, would it be wise for me to sell every coin I'm holding before end of year? That way I'll be able to at least show that I a) spent X dollars on crypto and b) ended up with X dollars at the end? This would give me a clear gain/loss that I might not be able to easily figure out if I'm holding some coins across tax years.
