The answer to this is easy and I am surprised you do not know it already. The founder of Bitcoin, named Satoshi Nakamoto is believed to own at least 500,000 Bitcoins, with some estimates putting this figure at higher than 1,000,000 BTC. This would make him a multi-billionaire and the largest holder of Bitcoin worldwide. You can read his earlier posts here on this forum, although he disappeared and has not posted in years.
Oga I will be glad if you can link me to the post you just mentioned, the post of one of the wisest man on earth "Satoshi Nakamoto" , if you do I will forever remain indebted to you.
