You think volatility is your only enemy? You're wrong.
The real predator is hidden in the order book. It's called slippage.
When you enter a market order on a low-liquidity altcoin, you're not buying at the price you see. You're consuming the available orders, paying more with each fraction of a coin. A 2% expected buy can easily become a 5% loss before the trade even fills. For large orders, this bleed is catastrophic.
Low liquidity = high slippage = invisible tax. Always check the depth chart. Trade in tranches. Or watch your capital get silently digested by the market's hunger.
