What do we think of a time that may come when the fate of human survival will depend only on using cryptocurrency for buying and selling, because mankind may soon find Fiat currency is obsolete or of no value in their current environment perhaps due to world earth crisis or pandemic or war .
Your opinion is valid!
it can never be possible for cryptocurrency investment to be must for the future, let me quickly remind that cryptocurrency is an alternative currency to the fiat, cryptocurrency never came into existence to eliminate fiat, so be guided don't allow anybody to deceive you by saying that cryptocurrency investment will be a must in the future, so only invest what you can afford to lose in cryptocurrency, don't within your capacity.
