Just a reminder that XMR is indeed trackable. Very difficult to track, but as the most learned on OCT have pointed out, XMR no longer is 100% anonymous if someone/some govt has the right resources.
You're right. We've seen this mentioned many times here on OCT, even by some of the so-called experts. However, if it's a one-time amount of 70K, as the OP says, I don't think there's much to be worried about.
