Yes we don't know if crypto will stay for so long but even there's no assurance here like it turn to not well anymore still we need to take the risk here because we can do only the affordable for us to lose so we can easily accept that situation here so better to risk here like business in real life actually for me even they spread FUD or something bad about bitcoin still we need this in life that's why this is non-stop
That's true we don't know when this will last and we should be careful in investing as this has high risk. Invest only a portion of your savings in bitcoin to make sure that whatever the result in the end you still have money for your retirement.
