Soft staking means that there are no lock-ups on the coins or tokens you deposit, whether in an exchange account or in a blockchain network node. This feature allows investors to stake and trade their coins or tokens simultaneously.
Without lock-ups, you have the flexibility to place limited sell orders for your staking coins to profit from significant price increases, and stop-loss orders to avoid losses from sudden and unexpected market drops. In that sense, soft staking allows you to adapt to changing market conditions.
