Just got into Bitcoin, where do we even start?

My older brother and I have recently caught the Bitcoin bug and we both are somehow excited but also overwhelmed about the entire idea. Neither of us has any real experience with crypto, so we’re starting from zero.

I’m here because we have a bunch of basic questions like How should we actually learn about Bitcoin properly, should we buy some first and where’s the best place to buy it safely as beginners? Maybe these questions are even too advanced (how can one learn about this properly) ? We really don’t want to rush in and make stupid mistakes.

Any guidance would be massively appreciated.
