But why im still earning even I didnt recruit another investor?
Why im still able to take profit even im not an early investor?
This is a very right comment, a good example happened in three days ago till today. Bitcoin was at at 9100 three days ago and has risen to $9900. Since 10 years ago, people that can trade are able to always make profits. Bitcoin is also decentralized and very transparent than being fake like ponzi schemes.
Those people saying bitcoin is ponzi might have a bad experience investing. Because if you know how bitcoin works you wont have such mindset.
Some can have bad experience but it is not mainly about bad experience, they are completely novice and may not get what bitcoin is.
