# Bitcoin halving

## Definition

Bitcoin halving is the protocol event that reduces the block subsidy by half after a fixed number of blocks under Bitcoin's issuance schedule.

## What it means in practice

Halvings affect new BTC issuance to miners but do not directly cut existing wallet balances in half.

## How this concept appears in Terenval Wallet

BTC held in Terenval remains governed by the same Bitcoin ledger before and after a halving; the event changes mining issuance, not user ownership records.

**Important:** Do not confuse halving narratives or price speculation with a change to the number of BTC already controlled by your wallet.
