A friend of mine told me I could use my CPU to process bitcoin transactions (to "blockchain" - his words) in order to make some additional money while my home computer is running. After a few days of searching I finally found the https://bitcoin.org/en/download page where to download a blockchaining software. And here comes my question: is that requirement for 100GB real? I mean do I really need 100GB free space on my hard drive in order to run the blockchaining software or is it just a tentative figure for the size it might reach some day in the distant future?
You dont earn anything for running a full node these days, its entirely voluntary unfortunately. And yes you need around 112GB currently, but if you have a modern computer that is nothing, most of them come with 2-3 TB these days and in a year or two that will probably double. . If you own bitcoin then helping to secure bitcoin is a given in my opinion.
