Martingale strategy (馬丁格爾)

Risks of Using Martingale in Bitcoin

1. Unlimited Doubling:
   Market trends can persist longer than expected, requiring increasingly large stakes.

2. Volatility:
   While Bitcoin's volatility offers opportunities, it also increases the risk of substantial losses.

3. Capital Limitations:
   Doubling quickly escalates. For example:

   • 1st trade: $50
   • 2nd trade: $100
   • 3rd trade: $200
   • 4th trade: $400
   • 5th trade: $800
     By the 6th loss, you need $1600, which is over half your $3000.

4. Exchange Fees and Slippage:
   High trading frequency amplifies costs.
