As reported by Malta Today, the unnamed man had bought a bitcoin miner from local IT firm 3 Group, but found that the power costs were greater than the value of the bitcoin earned by mining with the device.
He therefore took his complaint to Malta's Consumer Claims Tribunal, saying the unspecified €2,600 ($2,900) miner was noisy and did not make profit.
Dario Azzopardi, CEO of 3 Group, did not contest the complaint and the tribunal decided that the customer should be refunded €2,000 ($2,240).
The tribunal said in the statement on Tuesday:
"The Tribunal noted that even though Mr Dario Azzopardi has been served with the Notice of Claim, the date and the time of the hearing, he did not attend the tribunal sitting. Furthermore, Mr Azzopardi did not submit a written response to this claim. To the Tribunal this meant that the trader was not contesting the claim.
