I would like to know which software/ apps or websites you guys use to track the BTC-Price. And another question: Should you denominate the btc-price in your own local curreny or in USD? Thx for your help!

Last year in summer, i started my bitcoin journey, trying to gain some knowledge about it. So I started searching on YT for creators who make content about Bitcoin. Unfortunately, it seems to me that there are a lot of bullshit-creators in this field. And so far now I have only found Bitcoin University who seems to provide good value. My question are: - First of all, do you know him? - Secondly, what are your thoughts about him? - Last but not least, do you have any recommendations for good educational resources? E.g. like other youtubers, podcasters or maybe some quality blogs and newsletters. I am open to any recommendations, including books. PS: I already own the book "Bitcoin and Blockhain - Basics and Programming" by Antonopoulos which I haven't read yet. Btw what a name, lol.
