Last week Binance moved almost 110K BTC to one of its cold storage wallets. This is the biggest unspent transaction output (UTXO) that exists today. The transaction fee amounted to 0.00126921 BTC, or $7 at the time of transaction
It was nearly $600M at the time.
The all-time biggest UTXO record still belongs to Mt. Gox with 500K BTC which was worth $1.1M at the time.
