If somebody gave me 10 Bitcoins for free I would just sell them all so I would have some money. Free Bitcoins are the same as free money you can just sell them. So I would be happy if I got them.
Thats not fair, if you are a good human with that 10 bitcoin you need to earn much possible giving your full effort. Then you can repay 10bitcoin to the one who provided it. This would surely create a good remark on you as well on your effort, sometimes leads to good business.
in fact no one is going to give a lot of bitcoin or 10 btc to others without doing anything? it is impossible?
unless you ask for a loan to others by 10 BTC. it might just happen. if I got the loan of course I should be able to grow it
if not. maybe necessarily to lose because I have to pay interest
