Bitcoin price is formed from the balance of supply and demand on exchanges, which, unlike stock exchanges, trade 24/7.
A sharp rise or fall in the value of Bitcoin cannot be limited by stopping trading as it is done on stock exchanges.
Bitcoin is not tied to any currency or other asset.
The amount of Bitcoin is known and is 21 million BTC. Coins are issued or mined according to the plan determined in the code, and depend on the number of generated transaction blocks. Today (April 2020), around 18 512 312.5 Bitcoins were put into circulation. The number of coins issued changes every 10 minutes.
On April 25, 2010, the first official sale of 1000 Bitcoins took place at 0.3 cents.
In May 2010, two pizzas were bought at the price of 10 000 bitcoins.
In February 2011, bitcoin cost was about 1$.
12 april 2020 (10.00 Moscow time): 1 BTC costs 6.840,10 USD ( Blockchain Stock Exchange)
Indirectly, the price of Bitcoin is influenced by halving, which reduces the issue of coins (reward to miners).
From the embedded code of the Bitcoin system, it is known that every 210,000 blocks are halving.
