Selling all crypto to make my taxes easier - UK

Will selling all crypto to make my taxes easier UK

I have quite a few crypto transactions across multiple exchanges and have to file a tax return. My income is below 50k this year so my capital gains tax will be lower than potentially in future.

Seeing as the market is doing well if I sell all of my crypto (and do not buy it back for 30+days) will it make my tax return easier?

Eg. I can just go through and only look at the money spent on crypto through bank transfer and the money cashed out. Avoiding having to use an online service or work out vale at time of purchase ect Thanks for your help!
