Ok I am convinced in BTC now. I have also read these two books to help me answer my own questions (and I strongly recommend newbies do so too)

1) https://www.amazon.com/gp/product/B08WZ4P1DY/ref=ppx_yo_dt_b_asin_title_o00?ie=UTF8&psc=1
2) https://www.amazon.com/Beginners-Guide-Bitcoin-Matthew-Kratter/dp/B08RRKNNBK/ref=pd_bxgy_img_2/146-6517537-4103230?_encoding=UTF8&pd_rd_i=B08RRKNNBK&pd_rd_r=44c97157-70a8-44d5-8007-0f5051bba704&pd_rd_w=jCQis&pd_rd_wg=Twviz&pf_rd_p=fd3ebcd0-c1a2-44cf-aba2-bbf4810b3732&pf_rd_r=F8NHFB334T4HJHCNJQ4M&psc=1&refRID=F8NHFB334T4HJHCNJQ4M

Golden rule from the book: NEVER SELL YOUR BTC (lesson learned the hard way.)

Now the $100 million question, what is the best price to start buying BTC?
