Even Science Fiction
The futuristic computers of Star Trek can perform “575 trillion calculations per nanosecond” or 570,000,000,000,000,000,000,000 calculations per second. Being generous and saying one calculation is the entire process to brute force a single Bitcoin address private key, it would take ~40,625,842,296,073,558.47 (40 quadrillion) years to crack the private key to your address.
570,000,000,000,000 * 1 Billion nanno seconds= 570,000,000,000,000,000,000,000 calcs per second
(2160) bitcoin addresses /570,000,000,000,000,000,000,000 = 2,564,037,960,229,654,242,462,604.9696777/3600 sec an hour = 712,232,766,730,459,511,795.16804713269/24 hours a day = 29,676,365,280,435,812,991.465335297195/365.242 days a year 81,251,239,672,424,893.608800015598413/2 (for a 50% chance) =40,625,619,836,212,446.804400007799206 years to crack your private key.
Thats just awesome!
