According to @EmberCN, a whale invested 15,000 ETH (worth $198,000 at the time) in SingularDTV's ICO in October 2016, acquiring 12.93 million SNGLS tokens (1.3% of the total supply). Despite SNGLS reaching a peak value of $0.4354 in 2018, representing a 28x gain, the whale did not sell. They held onto the tokens for over four years until January 2021.
