I will suggest you for the buy of bitcoin and then hold it for long , but be careful , wait some days to go the price down .
You should not go for investment Because In the current time investment are risky and no one trusted site is in my view that can pay us with return of sure profit .
Secondly , I will suggest you to collect Bitcoin/satoshi from the faucet sites like freebitco.in .
If you will start your work in bitcoin without loss then your mind will remain prepare to do better in the bitcoin to make big profit .
