Mixero, According to the
FAQs on the website, the maximum amount that can be sent is 250 BTC, but that's 100 BTC in the image posted in OP. You should edit one of them.
Now what if I wanted for more added privacy to send you Bitcoin and receive ETH or XMR?
The same question was
asked by hugeblack and it was
answered. I think you missed that.
Mixero is not an exchange and that's why they are not going to add such feature.
Regarding the integration of ETH: it follows the same mechanism. We are not merely a currency exchange platform; our core functionality lies in ensuring the anonymity of your transactions, whether in BTC or ETH. Thus, there's no need for us to facilitate direct conversions between ETH and BTC.
