The idea behind Cryptex Defi Staking where anyone can earn up to $35,000 in 3 years and $471,000 in 5 years is that, Cryptex has  a partner Bank that will provide a staking capital for all members who activate a staking contract for only $100 one-time out of pocket. 

The options are 3 years, 5 years and 7 years plan. For 3-year staking contract, the partner Bank will instantly deposit $30,240 into the member's account who has just paid the $100 handling fee and that $30,240 will be instantly visible on the member's dashboard and it is already staked, which will generate a daily reward of 0.1% to 0.3% on da daily basis.

All daily earnings will be automatically added to the staked capital daily for the period of 3 years or 5 years as it will be compounded daily to increase the capital. For 3-year staking contract, it could reach up to $65,000 when the staking term ends, and the partner bank will just take back the loaned amount, and the remaining balance will be $35,000 which is withdrawable by the member or the wallet holder. 

For 5-year and 7-year staking plan, the capital loaned by the bank is $43,200 and at the end of the staking term, the net profit left for the wallet holder or the member is approximately $471,000 based on the Cryptex presentation

Cryptex has been  in business since 2016 but during their early days, they do their business offline and with only a few selected individuals. So, not many marketers are aware about it. But in 2022, when they already have an online presence, marketers have started coming in and sharing Cryptex online. 

They first conquered Germany and other European countries the reason why it is still seldom heard in the US where many English-speaking marketers are based from. But in 2023, Cryptex has become popular in many US-based marketing platforms and there were already a few contents on YouTube sharing what Cryptex Defi Staking really is all about.
