Cracking this is, for all intents and purposes, impossible as there are more possible private keys that would have to be tested (2256) than there are atoms in the universe (estimated to be somewhere between 1078 to 1082). But this is true for many of the world’s most stable national currencies since leaving the gold standard, such as the US dollar and UK pound.
