For how long should people understand the importance to have bitcoins for emergencies such as this one?
They found it once they change their mind and stop from thinking it was a scam and useless stuff. Because as long as they are in that negative mindset, nothing will be able to see but all of the negative views of Bitcoin. However, I'd see no reason why we have to urge people from adopting this new form of the payment system as it was the first for them to learn it and give value to this new creation. I have no clue what is really in their mind but for sure, the doubts and worries make them afraid to try.
^They are afraid of the value of the dollar will fly away when they are holding BTC but the fact, but they only look at the disadvantage, they never look up the advantage of BTC and the wonderful technology behind it. It is obviously BTC considering financial freedom, there is no need for a third party to hold your asset but in fact, the most common problem, if we cash out fiat to centralized companies, is usually we encounter delays in the process the same on the bank. But at least we have options on how to protect our privacy while using BTC not like using banks to put our money there.
The financial freedom provided by BTC is an advantage that the banking system will not have, because banks are regulated by the government and all the money in the bank they can manipulate in any way. using BTC or holding BTC provides privacy and only the holder can control it. Currently BTC is the most valuable and most sought after digital asset due to its diminishing supply, in contrast to Fiat money, which has a supply that can continue to be added. Long-term investment in bitcoin will provide a fair return and there is no deduction for holding bitcoins.
