The total quota of coins in the cryptocurrency is set at 21 million by design; when the circulating supply approaches this number, values are projected to increase. Source: www.c[Suspicious link removed]m
Bitcoin's maximum supply is 21 million. Some other cryptocurrencies have their hard cap, examples are
Monero (XMR) and Dash with 18.9 million, and XRP and Tron (TRX) with a supply limit of 100 billion. Some other cryptos have unlimited supply limits.
Something like this is not happening for the first time, bitcoin is known to be a highly volatile cryptocurrency and what we have to consider most is the market supply and demand for bitcoin, the value of bitcoin if we are to consider that one as well isn't stable in recent days and the exchange rate is increasing more in value with BTC/USD, this is another good reason why holding bitcoin is more valuable than any form of currency because you will miss out any exchange rate opportunity than when you're holding fiat currency alone.
Bitcoin is the most stable cryptocurrency. Other cryptocurrencies are highly volatile because their prices can go very high in a few minutes and nosedive in another few minutes. But we hardly experience such with Bitcoin. Bitcoin is when more stable than some fiat currencies and even my country's currency is more volatile than Bitcoin. I can say that Bitcoin is quasi-volatile
