How many bitcoins are there

But halving reduces the number of Bitcoins released by 50 percent every four years. It's simple economics. The rarer a commodity is, the higher its value — albeit subject to its demand. This limited supply and increasing demand have pushed the value of Bitcoin up.

Governments are free to print as many dollars or rupees as they need but they usually do not print it beyond a limit as doing so will result in high and unsustainable inflation. Economists are still studying what impact the hard limit has had on it but, on the face of it, Bitcoin price has risen massively since it was launched over a decade ago. In , mining one block yielded 50 Bitcoins but the value was less then.

A year later, a person traded 10, Bitcoins for two pizzas. Following this, each block began yielding only 25 Bitcoins. The second halving further reduced that number to In , each block mined yielded 6. In theory, it is possible. Block rewards and transaction fees are the most important sources of revenue for miners—the former more so than the latter in the current setup.

High prices for bitcoin enable miners to cover operational costs and sustain business profits because they can sell their rewards stash in cryptocurrency markets. When Bitcoin is close to reaching its limit, the reward amounts may not be enough to cover operational costs at miners, let alone generate profits. If and when the supply limit is reached, Bitcoin rewards are supposed to vanish. In both instances, transaction fees are expected to pick up the slack.

The amount of and mechanism for these fees depends on the state of Bitcoin's network at that point in time—i. The former may incur reasonable fees to enable Bitcoin's use in daily transactions, while the latter scenario will have miners conducting fewer and more expensive transactions.

Another possibility being put forward is that of miners forming cartels amongst themselves. They might control supply to set high transaction fees or a fee amount that guarantees them a minimum in profits.

Selfish mining is another possibility. In this form of mining, miners collude amongst themselves to hide new blocks and release orphan blocks that are not confirmed by Bitcoin's network. This practice will delay production of the final block in Bitcoin's network and ensure high rewards for the new blocks when they are finally released into the network.

The formation of a Bitcoin miners' cartel is not a far-reaching conclusion. Such groupings already exist in other commodities whose supply is constrained or controlled.

For example, oil prices are influenced to a large degree by OPEC's production output. Prices in the diamond industry are also reportedly set by a cartel led by mining giant DeBeers. The most valuable and useful aspect of Bitcoin is its network. Distributed ledger technology is a technological solution to the time-consuming bookkeeping and accounting that characterizes most financial transactions today.

If Bitcoin becomes popular as a medium of exchange in the future, its transaction numbers will surge. Past precedent has shown that there is a significant chance that the network will slow down. This is because Bitcoin's architecture, which relies on a distributed database to hold copies of massive ledgers, sacrifices speed for accuracy and integrity. In such a scenario, it is likely that Layer 2 technologies, like the Lightning Network, will become responsible for confirming a majority of transactions on its network.

Therefore, the cryptocurrency's actual network itself will be used only to settle large batches of transactions. A second possibility is that the number of transactions on Bitcoin's network falls.

Such a situation is possible when Bitcoin becomes a reserve asset. Trades involving the cryptocurrency will be few. Retail traders and small trading firms, who dominate its current trading ecosystem, will be eliminated and replaced by large institutional players and established trading firms.

They will conduct fewer and more expensive trades that will incur high transaction fees from miners. Bitcoin's inventor Satoshi Nakamoto designed the cryptocurrency to function as a medium of exchange for daily transactions. But its network has high transaction fees and slow processing times. Meanwhile, its scarcity and rising prices have become a magnet for speculative investors.

Their bets on the cryptocurrency roulette have led to volatile price swings in the asset class deterring serious investors away from it. Regulators have criticized its ecosystem as a Wild West. By the time that the last bitcoin is mined or close to being mined , Bitcoin may have a more defined identity that it does currently. Side channels, like the Lightning Network , may have increased its network's transaction processing speed and enabled its use as a medium of exchange.

Some countries like El Salvador are betting on such an eventuality and have made the cryptocurrency legal tender. El Salvador made Bitcoin legal tender on June 9, It is the first country to do so. The cryptocurrency can be used for any transaction where the business can accept it.

The U. Tesla reversed course on accepting Bitcoin in May , citing environmental concerns around the resources required for Bitcoin mining.

The increasing scarcity in its numbers will also have driven up bitcoin's price and the corresponding valuation of cryptocurrency markets.

Regulators tend to move quickly when increasing amounts of capital flows into an asset class, and it is likely that crypto markets and Bitcoin will also have come under the regulatory umbrella. That will be a sign for institutional investors to move into the cryptocurrency's ecosystem and stabilize its price swings with massive liquidity.

Bitcoin's 21 million supply cap is meant to control inflation that might, otherwise, result from an unlimited supply. But it has inflated the cryptocurrency's prices by making it a scarce commodity. When Bitcoin reaches the supply cap, it is likely that miners will shift from block rewards to transaction fees as their main source of revenue.

Development of side channels, like the Lightning Network, may result in Bitcoin's blockchain restricting itself to confirmation of large batches of transactions or ones that involve movement of significant numbers of bitcoins from one address on its blockchain to another. Bitcoin's identity—as a store of value and a medium of exchange—will also be more clearly defined than it is currently.

But none of these predictions are set in stone. The kinetic pace of developments in Bitcoin's ecosystem means that it is difficult to accurately predict its future.

For example, the cryptocurrency's protocol may be changed to accommodate the production of more than 21 million bitcoins. Or, it may fall just shy of reaching 21 million. The total supply of bitcoins is capped at 21 million.

When Bitcoin supply reaches 21 million, miners will rely on transaction fees rather than block rewards, which will have vanished by then, for revenue. When Bitcoin reaches the 21 million supply limit, it is likely that side channels, like the Lightning Network, will do most of the heavy lifting in confirming its transactions.

Bcash is a fork of Bitcoin with a few things taken out. Litecoin is also a fork of Bitcoin with the block time and mining algorithm changed. The truth is, no one really knows. We do know there are a little over million ether ETH in existence but we aren't sure how many. There is no real cap on the total number of ETH than can come into existence like there is with Bitcoin. Eth is not a fork or clone of Bitcoin like Litecoin is.

New bitcoins are mined every 10 minutes. The amount of time it takes a miner to mine a bitcoin will depend on how much mining power he has. Bitcoin has been around since You can see the tiny amount of data included in that first block below:.
