I was using the internet since 2010 but back then I never heard of bitcoin like the early people, will satoshi come back as a anonymous and give us leaked info on a new coin giving us a second chance to become rich?
1) Satoshi will never come back to ruin his anonymity.
2) You totally don't understand the concept of Bitcoin cause if you are you'll know that Bitcoin is not a product of getting rich over night without working hard or develop a good skill and knowledge about crypto.
Anonymous are welcome to comment on predictions for next 10 years, is satoshi working on a new altcoin ?
Not sure if he's but I don't think he have any reason to do that cause it may ruined his reputation and the trust the community have in Bitcoin.
