Why has Satoshi's vision for the Bitcoin as a peer-to-peer electronic cash system failed?
How did the investors ruin the vision which was similar to the Napster where data was shared at its own expense and received free of charge?
No it has not yet failed but due to the huge volume of transactions sent daily, it is encountering some issues and when it gets solved, it would get mostly solved.Its actually spammers who were responsible for network congestion with spam transactions.Another aspect is that most of bitcoin holders today view it as a high return giving asset and not ready to spend it or use it as a currency.
