As per their latest news page on the website, 30 days is minimum lock-in period for bonus coins but we can sell our active coins (which we buy to contribute) as soon as the internal exchange opens.

By the way, I have just invested in Ricona and I would appreciate if someone wants to register under me Here

Hello...
I think you're too fast to get that opinion. I hope you can know about the events of ignis. first out price ignis reach $ 10, but now?
I advise you don't be too interested in the price of the newly coin, wait for the price stable.

Thanks,
Hoeda

Simple and low

First of all you need to decide what bounty type do you want to participate in. Signature campaigns mostly require rank of Jr. Member and higher. Twitter campaigns require 500+ followers.

Next. You should find some reliable project with a bounty campaign. Go to some ICO tracker and choose the project with a bounty campaign. I recommend to use icodrops.com. There you can find links to bounty threads. If you want to find the thread by yourself just google "<project name> bounty bitcointalk".

The last but not least thing is to register to the particular campaign. The instruction how to do that you will find in the bounty thread.

Free bitcoins?  None.
