The difference though is that Enron insiders were engaging in immoral and illegal activities. Bitcoin on the other hand is provably not a scam; it is an existing and backed commodity.
Market manipulation as an insider is impossible, as there are no insiders; manipulation is only possible by attacking infrastructure or accumulating enough BTC.
Future bubbles and crashes are likely, but I predict it's going to continue to bounce back pretty much forever. Only if many major governments began to criminalize it, or if some new somehow "better" cryptocurrency came out, would it be in risk of complete deflation.
