Which Is The Best Way To Buy Bitcoins?

Not sure about the lowest fees but I’ve used coinbase (based in the UK) and it is secure and easy to set up. Accepts credit cards, bank transfers

i dont know what the best way is, but the easiest is coinbase, and if you need privacy you could use a mixer service. I have used EludeMail (it's a free e-mail provider on the Tor network, also has bitcoin mixer and monero exchange), did not have any problems.

I am a lazy person, so I just purchase via coinbase

I've only used Binance so far, but I understand there's a ton of other exchanges out there.

coinbase pro fees are so low
