In investments there are no secrets, you will tell everyone to to make the business have more cash flow and will be followed with success so your own investment would be more safe than keep it your little secret.
There are only a certain number of LTC mined each day. The more people who get involved, the less LTC each of them is able to mine. It's a case of deminishing returns and so it makes little sense to have "reflinks" for real mining operations.
When you see people being rewarded for recruiting new people to "invest" in a "mining" operation, it's likely a Ponzi, not a real mining operation.
To put it simply: suppose you have 50% of the LTC hash rate. You earn 50% of the LTC that are mined. Now suppose you recruit a bunch more people and you double your hash rate as a result. Do you now have 100% of the hash rate? No, you don't. You have only 66% of it. The original 50% is now only 33% of the total, and the new recruits are also only 33%. By recruiting more people your own profit has dropped.
Calling others stupid, if you have made over 10k us$ in 6 month with an investment of 6,000 us$ as a hobby besides your main job you can call me so.
Thanks. But can I take a rain check?
