Before staking NGM tokens it is important to understand:
There is a 21 day unbonding period (“lockup”) for staked tokens.
There is a risk of losing 5% of tokens staked with a validator that double signs. A validator can only do this once.
There is a risk of losing 0.01% of tokens staked with a validator that goes offline. This can happen multiple times.
It is generally advisable to:
Reduce risk by diversifying between at least a handful of validators.
Explore and consider the operational track record of validators before staking with them.
