Let's say I create the longest Blockchain for Bitcoin ever (let's assume it's possible). And then I add 50,000 nodes to the Bitcoin network and I use the aforementioned chain, wouldn't I be able to deceive everyone? Bitcoin trusts the longest chain, so if I have the longest chain and own majority of the nodes, wouldn't I be able to convince others some account has any amount of Bitcoins I desire?
If it's not possible for Bitcoin for some reason, is it possible to do the same for a cryptocurrency that was created recently?
Sorry for the stupid question, and thank you very much.
