When i flashbacks far 2013 and 2014, within that range far back i remember how people were castigating bitcoin as a means of extortion of money, and also a means of scamming peoples money, but today everyone is interested to invest in cryptocurrency and more especially in bitcoin, because from what i observed from little bitcoin seminar program i hosted in my geographical domain even a nursing mother that is approximately forty to forty eight (40-48) years is interested to invest with bitcoin and children in school is already knows what is bitcoin, so with this length of bitcoin awareness in my society i think BTC can stay till infinity.
I totally agree with you, the basis upon which the conclusion that "bitcoin can stay till inifity" was drawn is weak. I also so think the content of his post really doesn't justify the topic.
I understand that Bitcoin has come a long way and there's a very high possibility it would stay longer. What I am sure of is that technology today isn't what we had many years ago neither would it remain the same. I believe Bitcoin will strive in future but not without a competition.
I am saying Bitcoin might stay for long maybe not till infinity we can't say.
