We do need bitcoin because bitcoin is life for those who are crypto addicts. There are things that we know as part of our life. So I think bitcoin is not just decentralized and digital currency but it is also a possible lifestyle of everyone. The habit to do the given task by the campaign or by the admin.
Actually Campaigns are just there for advertisement certain managers would hire you to put on there campaign signatures and give certain task on what to post and how many post you will need to make, You can sure think of it as your work, But you can not call this a lifestyle and bitcoin is not a lifestyle but a currency you are just making money towards it because it is volatile in value.
