@glen-hodl, £250k is... well... substantial. Would you care sharing your strategy in terms of how you got to £250k, any hiccups, lessons learnt for people with smaller portfolios?

EDIT: What are you doing to make sure you pay tax as required? I am slightly confused if I need to worry about it if I am not cashing in any of my cryptos into FIAT (I am trading crypto-crypto).
