The biggest scam in the crypto world is overvalued token unlocks.

This can cause all participants to lose money.
Those who short or go long with contracts basically can't make money in a slow, gradual decline because there's no explosive surge or plunge volatility.
Holding spot assets and waiting for prices to rise often results in the classic boiling frog scenario.
During bear markets, project teams can keep selling tokens to dump the market.
In bull markets, they can sell at break-even because the token is initially valued to match a bull market.
Retail investors neither benefit from the gains of a bull run nor escape the -95% losses in a bear market.
They also can't profit through contracts because there's no volatility.
This is arguably the greatest invention in the history of financial plunder.
