Im not buying bitcoins, Im earning Bitcoin in bitcointalk by joining signature campaign thats the only im doing. Never buy any cents. Because im not rich, i cant afford to buy bitcoin. Im here to earn bitcoin not to buy bitcoin. And thats the only thing im doing as of now without buying bitcoin. I have .2 bitcoin.
Thats also a good way mate, even your not buying bitcoin atleast you are earning from it. Even you are only earning bitcoin you can always maximize it and you can make it grow either you use those bitcoin to do in trading and youll gain profit to it. Just keep up and do things to earn coins and expect to rise its price in future which can make you more profit.
