Captial gains tax rant

I’ve been in the crypto scene since 2020 and have purchased and traded multiple cryptocurrencys over multiple exchanges.

I have (stuidly) avoided looking into taxes specifically CGT.

The bull run couldn’t come any sooner but with the CGT being lowered yet again to £3000 I feel overwhelmed with the thought of trying to work it all out. I’ve made well over a hundred transactions and in my early days I used a couple of exchanges I no longer have access to.

I’m not looking advice (although any is welcome) I’m just wondering if anyone else is feeling the same sense of dread when it’s finally time to cash out?

Edit: I’m from the UK
