  The rise in adoption of cryptoassets has brought many new and inexperienced
investors in the cryptocurrency space. These investors can be disproportionally
influenced by information they receive online, and particularly from social
media. This paper presents a dataset of crypto-related bounty events and the
users that participate in them. These events coordinate social media campaigns
to create artificial "hype" around a crypto project in order to influence the
price of its token. The dataset consists of information about 15.8K cross-media
bounty events, 185K participants, 10M forum comments and 82M social media URLs
collected from the Bounties(Altcoins) subforum of the BitcoinTalk online forum
from May 2014 to December 2022. We describe the data collection and the data
processing methods employed and we present a basic characterization of the
dataset. Furthermore, we discuss potential research opportunities afforded by
the dataset across many disciplines and we highlight potential novel insights
into how the cryptocurrency industry operates and how it interacts with its
audience.
