Many are living their businesses to turn to crypto with the mind of joining the trend and with the way crypto investment is been hyped lately many just feel its actually one of those easiest way to make money online and the funny part is most of them dive into this opportunity without any formal knowledge about how the system works.
I will say crypto isn't a safe Haven and there is no 100% guarantee in crypto investment although one can attest to the fact crypto isn't ponzi but yet it's not just an easy adventure its an ever learning business option that could be passively yielding and at the same time bankrupt yielding depending on ones approach.
If crypto was that easy to go by we would have had more than half of the world's population living very comfortably not giving much concern to their economic data any longer. But the truth remains crypto investment is more difficult compared to manual businesses
Safety is all relative. If you're living in a country like Turkey, where the leader keeps trying to interfere with monetary policy in a short-sighted way which causes huge inflation then a currency with relative stability would be very useful (even if it only had smaller inflation versus the huge inflation of your local currency). Some people do not see cryptocurrency as safe because it can wildly swing around in price and unlike what some people wish, it has limits on the amount it can rise because it needs to be a functional currency to hold real purpose in the world, rather than just a dormant asset which relies on everyone believing it will hold a certain price level.
