Long time lurker!

Hi I'm a middle aged bloke from the UK with little to save.

Can anyone direct me to a unbiased link to how one with little income to save to start investing in bitcoin legitimately without the use of unregulated brokers like FTX, Binance, coinbase and the like. I'm based in the UK and have a good general knowledge of IT. But where to start! I know this must have been asked a million of times but I sense that with bitcoin and somepart Etheriuim could be to big to fail by this point and anything that I can do to move away from the forced model the central banks are constructing would be helpfull to me. Thanks and keep up the good work
