yes, even walking can help you earn crypto. and now there are clicker games as well. when i say losing all the money, i mean those who use some leverage. otherwise unless crypto goes down 100%, one will not lose their investment entirely. and corrections are always steep in this space. an average correction would be 20%-25% which is good enough to wipe 33% of your gains. however, there is a good enough probability that the investment will generate positive returns in the long run. I remember buying bitcoin at 20k for the first time, only to see the price fall to 3k. :) I am +ve on that position. At one point that position was valued 3x+!
