What do the different transaction types mean?

Each row in your history says what happened: coins you bought, a tip you sent, a membership, an unlock, a boost or VP bonus, or a reward from Vergr.

• Coins: coins you bought.
• Tip: coins you sent to a creator.
• Membership or plan: a creator membership you bought or gifted, or a Lite or Pro plan.
• Unlock: a paid stream, an event ticket or a paid post.
• Boost and VP bonus: a boost or VP multiplier you bought.
• Reward: coins or VP Vergr gave you, like your monthly plan coins.
