Bitcoin yes or no
Bitcoin Cryptocurrency have been on the rise for most of their period, reaching a record low of $ 20,000 per BTC in less than a decade. Although the Cryptocurrencys is currently trading at half its maximum record price, it is one of the largest active currencies in the world and has become one of the most profitable assets of all time in a short period of time.
Despite this steady growth and the unbelievable numbers, bitcoins and critics of Bitcoin have always argued that sooner or later it will decline and become worthless forever after a heavy fall. For example, Calvin Ayre, a supporter of the BCH project, recently tweeted that Bitcoin was "completely worthless," while Warren Buffett, one of America's most well-known successful investors, repeatedly stated that all available cryptocurrencies (including Bitcoin too) are worthless.
But is there really an event that causes the entire value of Bitcoin to be lost and its price to be zero? 
The answer to this question is yes, and that there are many events that will eventually lead to the devaluation of bitcoin.
Yale University economists Yukun Liu and Aleh Tsyvinski have published a report titled "Risks and Profitability of Cryptocurrencies" in 2018, examining the possibility of bitcoin falling in just 24 hours.
Using bitcoin profitability charts to look at and calculate the probability of a major catastrophe that would ultimately reduce the value of the cryptocurrency, the two economists concluded that the probability of a catastrophe occurring and bitcoin falling was something between "zero." Up to 1.3%. At the time of writing, they explained that the figure was about 0.4 percent. To better understand this number, he also noted that the probability of the euro falling and depreciating to zero is about 0.0009%.
Some believe that the Bitcoin cryptocurrency will eventually fall to zero dollars because it has no intrinsic value. However, although bitcoin has no intrinsic value, it is supported by customer trust and sophisticated mathematical calculations. This approach is somewhat similar to the US dollar, currencies that were previously backed by gold and are now only supported by the government (while some believe that the US dollar is supported only by "government debt").
A similar event
A similar phenomenon occurred recently, when the Bank of India (RBI) announced in November 2016 that the counterfeit 500 and 1,000 ruble banknotes were no longer valid due to their proliferation and increase. Although these banknotes can no longer be used as a common currency in India, their value is still preserved as a work of art or souvenir.
What is your opinion about the proposed scenarios? Is it possible for Bitcoin to fall to zero or be replaced by another Cryptocurrency?
