Bitcoin, born in 2009, is gradually released through mining activities. Its scarcity—capped at 21 million coins—has been a key driver of its price appreciation, attracting investors and miners alike. Recent surges in Bitcoin's value have accelerated mining participation, further speeding up its extraction rate.
Key Statistics:
- Total Bitcoin Supply: 21 million
- Already Mined (90%): 18.89 million (circulating in 12 years)
- Remaining (10%): To be mined by February 2140 (per halving schedules)
- Current Market Cap: ~$897 billion (largest cryptocurrency)
Why Mining Slows Down
Bitcoin's protocol halves mining rewards every 210,000 blocks (~4 years), a process known as "halving." This reduces supply influx, extending the timeline for the final 10%. Miners will increasingly rely on transaction fees for revenue.
Performance & Controversy
- 5-Year Growth: 5,121.37% (per Barchart.com)
- Criticism: Some Wall Street investors label Bitcoin a speculative bubble, cautioning retail traders.
FAQ
1. Why does Bitcoin have a 21 million cap?
The limit is hardcoded into its protocol to enforce scarcity, mimicking precious metals like gold.
2. How do halvings affect Bitcoin’s price?
Historically, reduced supply post-halving has correlated with price surges due to heightened scarcity.
3. Can the 21 million limit be changed?
It’s theoretically possible via network consensus, but altering this core feature is highly unlikely.
4. What happens after all Bitcoin is mined?
Miners will transition to earning income solely from transaction fees.
