What is the Bitcoin halving?

Roughly every four years, the number of new bitcoins created is cut in half. It's built into Bitcoin's code — and it's one of the most talked-about events in crypto.

How the halving works

New bitcoins are created as a reward to miners for each block they add to the blockchain. Every 210,000 blocks — about four years — that reward is cut in half. This continues until the total supply reaches 21 million BTC, expected around the year 2140.

Why it matters

Each halving reduces how many new coins enter the market each day. With demand unchanged, less new supply can support prices — which is why halvings get so much attention. But price depends on far more than supply: global money conditions, regulation, and the mood of the market all matter.

What it means for traders

For short-term trading, the halving is background, not a signal. What matters day to day is whether Bitcoin is trending up or down — which is exactly the filter Signava checks before every spot signal. See why Bitcoin decides every trade.

Frequently asked questions

When is the next Bitcoin halving?

The next halving is expected around 2028, after block 1,050,000. The exact date depends on how fast blocks are mined.

Does the halving make Bitcoin's price go up?

Past halvings were followed by bull markets, but many other factors were involved and past patterns don't guarantee future ones.
