I have seen bounty hunter doing well, I have also seen people who do not participate in bounty and are making it well with trading alone, but I have never seen anyone around me being involved in mining, I learnt mining is more risky and cannot just be done alone, and if you even attempt it probably with your android, you may end up wasting your time and not even making it as the traders and hunters. It tend to take a massive effort to be successful in mining, you need good electricity,good mining wallet, computer with good capacity, and some other gadgets.
Mining is not anymore for an everage joe, it has already taken by the big miners as they have good equipment and they can invest on it.
We are not in the early stage where a small specs of computer can still mind bitcoin, things has change, this is already the game for the big boys.
On the other hand, if you are thinking of trading, you also need to invest a capital for your regular trade, there's a risk and with lack of knowledge and skills, you will still fall. However, one can learn and improve his skills in trading, so it's always possible to succeed as long as you know and you take the risk.
Considering all this, which of all the participation do you see as least demanding and easiest?
Bounty hunting is the easiest though as you don't risk any bitcoin here, but I don't think it's good idea to focus on it if you want to make a decent amount fo money, probably trading should be the best choice, but it's never easy
