On Bitcoin/Gold/etc...
It seems like every large bubble is started by a big order with huge slippage. Same thing for each bubble crash, but in reverse. Whoever triggers one of those makes a fucking mint. So, does that make slippage good, contrary to for example slippage when buying a stock?
Slippage and making a "fucking mint" off of said slippage are both a symptom of low liquidity. If bitcoin liquidity ever becomes better, both slippage and the profits from triggering slippage at the correct time will become less.
