So, to claim, I have to sign a message using the wallet.
Any security concerns about this?
As long as you move your coins and use TOR when showing them your signature it should be fine. You can use a VPN but then the VPN provider will know who you are
seems like a GREAT way to link btc addys and track them out the wazoo. even after moving them they are now linked forever to the airdrops garbage.
fine if you dont care about privacy
Maybe you can route your shitcoin wallet activity through TOR and send the shitcoins to an anonymus exchange
and change them in some other coin. But surely
some trace will be left somewhere, like anything you do online.
I think that your BTC themselves are traceable, at least as soon as you cash some of them out. Too much chain analysis going on for too long. You won't have 100% privacy.
If you have a way to cash out
bigbigger chunks of BTC with 100% privacy, please let me know
