The mysterious founder of Bitcoin was Satoshi Nakamoto, which is most likely a pseudonym. Mr. Sakamoto disappeared from the public about 1 year after Bitcoin's release, and is considered dead by now. Bitcoin's development has been taken over by a team of 100+ highly skilled developers worldwide since and has grown beyond anyone's expectations. It's been a rough but amazing journey, with the occasional hiccups and obstacles of a completely new and revolutionary technology, but a constant inspiration to thousands of 'wannabe Bitcoins' and the overall new technology sector Bitcoin's technology is based on - blockchain technology and the tokenization of assets. Due to it's unique features though, Bitcoin is considered as a completely new asset class comparable to gold (thus also dubbed as 'digital gold') and could one day even be used as a collateral for state-level currencies.
As an investor in Bitcoin (BTC), you can rely on a groundbreaking technology which implications usually take months (if not longer) to fully grasp. I've been in the cryptocurrency space for longer than 2 years by now and am still learning and more amazed the deeper I dig into Bitcoin.
