It will be a great idea for Yo-Ex to introduce a faucet where its coins will be earned freely too. It will equally increase the level of awareness just like this signature campaign is doing.
You want yobit similar faucets for earning on daily basis ? Have you ever got chances to withdraw the coins you had received from faucets ? But unfortunately I never made any satoshi out of them. I remember I tried to convert some free altcoins but I got error message of trading volume less than 10k satoshi is not allowed.
I believe faucets on exchange is not a good idea unless otherwise there will be an option to play dicing.Not necessarily having the free coins on the exchange site. They might donate them to sites that can they give it out to participants. And yes, I have claimed and redeemed some satoshis. About 25,000 satoshis which was an equivalent of 25 American cents. I must admit that faucets are generally a waste of time.
Well the fact that faucets are just a waste of time would make traders do it while watching the price of a certain coin to go or down. So maybe I rather suggest a dice or a minigame on it to make people not get bored while watching the certain coin.
