Say it again! Contracts are only suitable for short positions. If you want to go long, why not use spot trading? Being stuck won't lead to liquidation. You just earn a little less.

The purpose of contracts is to hedge spot trading, but firmly believe that selling high is a must.

Spot trading is clearly not prone to liquidation. Yet, there are always thoughts of getting rich quick with several times returns. If you can compound daily at 2%, you are already a king.

Contract grid shorting is to provide everyone with high-level quantification. Why not do quantification to harvest when altcoins have no real value? If you're afraid of being stuck in spot trading, just do spot grid trading.

Assuming 1000U, contract grid 200, spot grid 500, DCA 300, there’s really no need to go all in and fantasize about getting rich.
