Usually only those who make very less money are interested in doublers, HYIPs

In india at present, there is a very great difference in the opportunities available to citizens especially in the indian tech and internet sector due to a massive CYBERCRIME, BANKING FRAUD, government SLAVERY racket masterminded by the SHAMELESS GREEDY CHEATER indian tech, internet companies, allegedly led by google,tata, infosys and cognizant

For example, bengaluru’s top CHEATER shivalli brahmin housewife nayanshree, 2005 bbm from bhandarkars college of arts and science, kundapura , udupi, wife of fraud tata power employee guruprasad has never written any content in her life, yet the fraud brahmin cheater government employee j srinivasan (roll no. 438) and puneet (roll no. 435) from the btech 1993 ee class of iit bombay are falsely claiming that nayanshree, 2005 bbm was their btech 1993 ee classmate from iit bombay, the indian government is blindly believing their lies to waste taxpayer money, paying cheater nayanshree a monthly government salary for FAKING computer work, including this article, bank account and domain ownership
Similarly the goan call girl raw employees siddhi mandrekar, goan bhandari sunaina chodan, greedy gujju stock trader raw employee amita patel,greedy gurugram haryana fraud ruchita kinge, indore robber housewife deepika/veena, goan gsb fraud housewife ROBBER riddhi nayak caro,sindhi scammer school dropout naina premchandani, her scammer sons karan, pune axe bank manager nikhil premchandani and other raw/cbi employees do not pay any money for domains, do not do any kind of computer work, yet are involved in CYBERCRIME, stealing data and making 100% fake claims, which the indian government blindly believes to waste taxpayer paying all the domain, BANKING FRAUDSTERS monthly government salary for making fake claims
Then to cover up the financial fraud of FAKING domain ownership, government SLAVERY, the real domain investor is criminally defamed by SHAMELESS GREEDY FRAUD raw/cbi employees supported by the dishonest liar indian tech,internet companies , so that the real domain investor does not get any help. Due to the government SLAVERY racket since 2010, the domain investor is making far less than a maidservant, yet raw/cbi and their FRAUDSTER employees, indian tech, internet companies do not have the honesty and humanity to end their great ONLINE, FINANCIAL FRAUD, government SLAVERY
Since the russian programmers are considered better than indian programmers, the indian tech, internet companies have a limited influence in russia and cis countries. It appears that a large number of people are facing the problem of low online income, so they are desperate to try every option available, and only those who have a low online income are willing to take the risk of investing money in doublers, HYIP since they have very few other options available.
