Investing wouldn't require you to fork in thousands of dollars in resources alone to earn considerable profit. The thing about mining is that it is only profitable when there are lesser people on the pool, and since millions of people are already mining nowadays, there is a good chance that your standard rig wouldn't be so profitable after all. Investing on the other hand doesn't require that much money, just a good enough capital for you to start you journey, from there the path is already laid in front of you, and you just need to make wise decisions to profit.
Mining VS Holding if I choose for now, then I will choose holding, with holding we can search for coins through a bounty campaign or airdrop so we can increase our profits.
For Mining at this time, I think there is still a chance to get multiple profits, it's just that equipment and maintenance costs money so that it will reduce mining income.
This is funny but it makes sense for the beginner investor to scour the vast expanse of the internet for paid promotions and bounty campaigns, however, keep in mind that you may also need to invest a couple of your hard-earned dollars as well because as of the moment salary for such jobs don't sound so great. That's what I did, and it had helped me develop more into the investing scene.
