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when the Bank of India (RBI) announced in November 2016 that the counterfeit 500 and 1,000 ruble banknotes were no longer valid due to their proliferation and increase.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?
Trying to put on similarities between fiat and Bitcoin is not really that right nor a solid thing for you to make it as an example but in the talks about on Bitcoins fall and becoming worthless then theres always a possibility
because we do know that nothing do last forever and there would be always a chance that it can be possibly overtaken by much better good coin or project in the future this is always the risk involved
when you are someone who do really keep bitcoins for long term aspect but somehow we can really make such support due to the current situations that we do witness on where bitcoin does have a big community or supporter which you can presume that it would really last even on further years to come but we should really not remove on our minds on the possibilities.
