is any intresting to get in one file all : BTC_addres, r,s,z, date_time_stump,public_key ?
blockchair.com provides this data at a price cheaper than 0.15 BTC, and if you buy a VPS with a paid blockchair.com package, the costs will definitely be much cheaper than 0.15 BTC.
If you analyze this data and extract something useful from it, as happens with Glassnode, its value may increase, but it will definitely not reach $9,000.
