So bitblender.io is safe to use and not .org?
Because i'm not transferring much BTC I'm worried when chip mixer breaks them into smaller parts that it won't meet the market places minimum deposit amount.
The one with the .org domain is a phising version. If you send any BTC to the fake one, they will be lost forever.
According to the ChipMixer announcement thread, there are chips with 0.001 BTC, 0.002 BTC, 0.004 BTC and so on till 4.096
BTC. You just need to check how much you want to mix before sending any amount.
