It has to be him (judging by the amount of BTC in there, I'm pretty sure this is the case), otherwise that means his wallet is compromised.
If it is for him, according to his last comment that the payments for the last week will be sent, did you receive any payments for the last week?
As ChipMixer has been seized, the campaign is now ended. Outstanding payments will be made later this week.
Also, the cost of managing one week in the campaign is 0.4, and the amount of 1.3 is sufficient for about 3 weeks. Should it be refunded to ChipMixer
*, or should it be to DarkStar_ or what?
I think this address bc1q29xpuw8mx9933xed7t6r03yge42zf2rqmevntm belongs to a government agency given that the balance has about 50 bitcoins
* I don't know how that will happen.
