From my short experience of 3 years (ending last year), the answer is NO. I "invested" (invest is a strong word here, I would say) in initial coin offerings, in old "established" coins, in other crypto as-sets. Fortunately, I did this with small amounts of money, so the losses were not astronomical. But never the less, it was a PURE GAMBLING! I would have spent better time (and who knows, maybe better luck) in a casino. I wouldn't recommend this. If you want a passive income, consider something else. Now I sell stuff online in the weekends and in parallel to my day job, and I am quite happy from what small I make extra.
