For each of the options, feel free to leave a comment to describe your role in greater detail.
I'm looking forward to your replies!

which I do when following blockchain is one of them is to find additional income by following an ICO project. Such as Signature Campaign and Social Media Campaign. The results are pretty good for me when compared to ICO investments that are not necessarily profitable
