Romania is an EU member, so your node ships under the same network neutrality and routing transparency rules as any node in Frankfurt or Amsterdam, but Bucharest data centres carry meaningfully lower bandwidth pricing. That matters when your node pushes 30-60GB per month of block relay and Compact Block traffic to peers.
The legal posture also helps. Romanian courts struck down blanket telecommunications data retention years before the rest of the EU caught up. A full Bitcoin node is not illegal anywhere, but a jurisdiction that treats network metadata as a constitutional concern is a safer home for a node that broadcasts your transactions.
Latency-wise, Bucharest reaches Frankfurt in roughly 30ms, Moscow in 50ms and Istanbul in 25ms. Your node ends up well-positioned in the Bitcoin Compact Block relay topology.
