Out of those mentioned above the only thing I am doing at present is HODLING. I am a lazy person so I prefer keeping my investment at bay. I want to try trading but I am not sure if I could keep up with the process, sometimes it is really hard digest every information you see online.
Years ago I tried the FAUCET. I did get a few BTCs there but then it is so little that you can't notice the impact on your coffers

What I realize today is if you want to earn more, you need to take a risk.
HODLING can be very challenging for any individual who does nothing for a living I am quite sure you have other means of earning or source of income however a hodler might find it difficult because of the pressure of meeting up with daily needs such as buying of stuffs, foods, paying of bills etc, above all its better to learn trading of cryptos which can invariably provide a steady source of income however with a higher or bigger risk.
Personally I had already switched over to binary trading as well as learning forex trading as a result of few available and highly competitive nature of signature campaigns in the forum these days.
