In order to vote, you have to be a registered user ( follow this link https://fyrus.pro/register ) and hold at least 1000 FYR.
FYR can be acquired by signing up, depositing either BTC or ETH, and exchanging them for FYR in the slide in account menu under the "Get FYR" tab.
To access the slide in account menu, please click on the profile icon located at the top right corner of the main exchange page after logging in.
Each user can cast ONE vote for each project and each vote costs ONE FYR. Max. 5 votes per account per week. Once voted, your FYR is NOT refundable.
For a project to be qualified, the project has to receive a minimum of 1000 votes.

So we have to buy FYR essentially.
