If I have 0$ at the moment can I make 100$ in 2 or 3 months? How?
What if I deposited 20$ .. Can I make them 100$ in less time?
Try participating in bounty campaign, you just need an account to get profit.
Suppose you join the signature campaign, then you need a jr member account. And after ico is finished you can get your reward.
Or try to join the airdrop, you only need a bitcointalk account and an email then follow the instructions.
You can get his coin after they distribute it.
