ok I'm going to switch up my pension stocks (SIPP for UK bros) to 1/3 GLXY, 1/3 ETH DATs (BMNR SBET) and 1/3 TSLA what could go wrong

i only ever put in one big lump sum of cash into my pension in 2019 because i had money in my company and wanted to do something tax efficient. That all went into an ETH ETN (coinshares) which did like a 20x despite fees by 2021 peak. Must have one of the best performing SIPPs in the UK purely by accident
