What if Bitcoin was reimagined today, under modern cryptographic assumptions, using a principled minimalist architecture designed for long-term auditability and zero-trust adversarial environments?
Bitcoin as all things in life on this planet, need development and improvement but it doesn't mean Bitcoin has to change its entirely.
You can get many examples from altcoins that either forking from Bitcoin source code or copying from Ethereum, with their Loud and Noisy Mission of becoming "A Bitcoin killer" in history of blockchain and cryptocurrency industry. At the end, those projects were abandoned, died and since 2009, with thousands of altcoins have ever been created and will be launched more in future, there is No Single Successful Bitcoin Killer.
How Many Bitcoin Forks Are There? You will be surprised!!!How many cryptocurrencies have failed?Altcoins need to reimagine themselves, not Bitcoin.
