Increased fingerprintability is not at all relevant here. Consider
adding uBlock Origin to the Tor Browser as an example of increasing the
fingerprint left by Tails users. Websites could check whether a client
using Tor is blocking ads to narrow down that the user is a Tails user.
The coin selection that I recommend changing happens entirely offline.
No remote servers are involved in the creation of a new transaction.
Once the transaction is broadcast to the Bitcoin network, the
fingerprintability actually goes down as the transaction looks more
generic. Remember that all transactions will have inputs and outputs
that appear the same to the network. The change here is selecting inputs
that reveal less about the user’s total bitcoin balance.

Is anyone else in favor or against this change? My attempt is to make
privacy a default option in Tails.
