- Small outputs Good
No output costs more to spend than it holds at typical fees. What dust is
- Address reuse Info
Seen in 76 transactions. Repeated use of one address is publicly linkable. What address reuse means
- Address type Info
Legacy (P2PKH), the original address format. Relative fees depend on transaction structure. What the address types mean
- Unspent output distribution Good
The balance is spread across several unspent outputs. The largest holds 69%. What a change output is
- Activity Good
Active in the last week. What dormant, quiet and pending mean
