> Is this number for real? I can think of many actors for whom this is just small change, and who might have incentive to break trust in the Bitcoin network by successfully performing such an attack. Sorry if this is confusing - the attack cost is calculated based on the cost of hashing power from NiceHash * the global hash rate. If the 'NiceHash-able' column is <100%, NiceHash doesn't have enough hashing power to complete an attack (and thus the price is greyed out). This page [0] has more details. > Using the prices NiceHash lists for different algorithms we are able to calculate how much it would cost to rent enough hashing power to match the current network hashing power for an hour. Nicehash does not have enough hashing power for most larger coins, so we also calculated what percentage of the needed hashing power is available from Nicehash. Note that this ignores the fact that large mining operations could easily switch coins to carry out attacks. [0] https://www.crypto51.app/about.html https://www.crypto51.app/about.html
