Any advice/t

I follow crypto for about 3 years but not consistent enough and with 0 maturity or knowledge about them . I want to start learning about cryptos . I've never bought crypto before and I would like some tips on what to focus on learning and what sources to use to learn..and after that buy some crypto

I dont expect to be rich or anything ( at least soon enough) but I'd like to spend some extra money on that as a hobby and why not learn from that and why not take some profits someday

If you have some time and feel like it I could use ur tips

Thanks in advance
