Can someone tell me anything about UK tax on withdrawals? I just took out 20k give or take do I need to fill out a self assessment form? The first googling I've read so far is this https://www.gov.uk/government/publications/revenue-and-customs-brief-9-2014-bitcoin-and-other-cryptocurrencies/revenue-and-customs-brief-9-2014-bitcoin-and-other-cryptocurrencies which says it isn't taxed? But it is an older document and I'm sure I've seen people mention it needs to be?
