Primary Market | What do people mean by “token lock-up”?
Team and investor lock-ups are usually outlined in the tokenomics document. Some are enforced by a vesting contract, while others are just written agreements.
On-chain lock-ups let you check on a block explorer how much is locked and when it unlocks. For lock-ups based on written agreements, you have to rely on the team’s credibility.
Subscribing to fixed-term products with $BNB is also often referred to as “locking up.” Currently 693.54.
Try to invest only money you can afford to lose without it affecting your life.

Just my personal opinion—don’t take it too seriously.
