Ways to participate in each round (users can participate in many rounds if meeting the requirements):

Process

Step 1: Users can fill in Cybex [Subscription Intention Form] :https://olddex.cybex.io/eto and read the rules carefully. The ETO purchase includes four rounds. Please create subscriptions based on actual situation.

Step 2: In round 1 and round 2, a lottery-like method is adopted to determine ETO allocation. Users can process the locking-up of CYB within a period after filling in [Subscription Intention Form]. CYB volume determines the amount available to purchase, which means the more CYB you have, the more likely you win.

Step 3: Please wait for the results patiently after the subscription. We will announce the winners and the user accounts that meet ETO Rush Purchase requirements one day before the Purchase, and unlock all participants’ CYB.

Step 4: You can Rush to Purchase on the ETO day based on your allocated amount. And tokens successfully purchased will be released to your account in real time.

Tips:

1. You have to fill in [Subscription Intention Form] first before making transfers to the specific accounts. Otherwise, it is invalid. The amount of invalid transfer will be refunded to the original account within 3 working days after the end of ETO.
2. KYC is not needed in the ETO subscription.
3. Please unlock your CYB in [Lockup Assets] on June 14th.
4. The amounts of DOT are all calculated and allocated in integers.
5. Cybex has the right of final interpretation of the rules and to adjust it as appropriate.
