Average transaction speed of 45 cryptocurrencies with the highest market cap as of December 2025 (in minutes)

The estimated time with which Kraken would confirm a deposit of certain cryptocurrencies varied from between near-instantaneous to up to several hours. Bitcoin, for instance, could take around ** minutes—depending on the fees involved—whereas tokens like Cardano or Solana could be handled almost immediately. The transaction speed matters as it indicates which cryptocurrency is more efficient. A higher efficiency means that the blockchain underneath the coin is more capable of transferring data from one party to the other and confirming transactions. Transaction speed can be influenced by various factors, including block time, block size, transaction fees, and network traffic.
