I will use the bitcoin to buy some Etheruem and then buy into Slock DAO. After I have made some profits, I will give 10 bitcoin back.
I think if someone ask you that i give you 10 btc or something, so it doesn't mean that he will give you that amount, he is just telling you that he have some amount of bitcoins and ask you some advice what the best way where he invest it.
You are right. This topic must be an imaginary topic but it would help any people to get an idea if they get some free bitcoins. Because many people are not getting prepared for the bitcoins they are getting/saving. This type of topics will help them to get some good preparation in advance on investment with bitcoins.
