$ETH An Ethereum ICO participant, silent for four years, has deposited 800 $ETH—worth $2.96 million—into Kraken, cashing in on a massive gain.

Originally snagging 8,950 $ETH for just $2,783 during the ICO, they now hold 1,780 $ETH, valued at $6.66 million. That’s a jaw-dropping $13.36 million profit, clocking a 4,803% return.

What’s your take—is this participant perfectly timing their exit, or holding that remaining $ETH for an even bigger payoff?
