Here's what it says on the crystaltoken.co website:

A contract can be activated from the Virtual Staking section of the dashboard, using CYL tokens or VCYL tokens. We remind that the VCYL currency is equivalent to 0.001 ETH and that is a virtual currency used in our platform to accumulate interests, referral bonuses and capital releases, and that can be directly converted to CYL tokens or used to open a new contract. Each contract is defined by a start date, an end date, and it receives a daily percentage of interests calculated on the amount in VCYL at the start date of the contract. We offer additional options such as pure reinvest and token bonus to increase the profit of the contract. Additional details can be found in the Virtual Staking section of the dashboard and in our whitepaper. The daily percentage of interests is shown in the dashboard and depends on the revenue generated by our trading operations. Daily interests are credited into the VCYL wallet, and they can be converted into CYL daily unless you decided to opt for the pure reinvest functionality. In order to withdraw daily interests, the user needs to convert VCYL in CYL tokens and then sell CYL tokens on the internal exchange, to obtain ETH. As an alternative, VCYL tokens can be directly converted into ETH at the rate 1 VCYL = 0.0005 ETH.
