Hmm AFAIK there are 2 giveaway here.
1. It is a weekly giveaway, called #FREESPINFRIDAY.
Usually they give 0.05 to 5 people each Friday. But only for this week, they are giving 0.10 to 5 people, so each people receive 0.02BTC or 20mBTC
2. A 200mbtc one time giveaway which the winner will be announced on 1st October
This is spot on, we're doing weekly giveaways of 0.1BTC (which we do plan to increase!) and then a much larger 200mBTC giveaway, no deposit or betting required giveaway for October 1st.
Check in with us
on Twitter tomorrow for the next 0.1BTC we're giving out.
