Show HN: Cost of a 51% Attack on Popular Cryptocurrencies
After the multimillion dollar Bitcoin Gold 51% attack a few weeks ago, I was curious what an attack like this costs against other currencies. I calculated the cost of renting hashing power from NiceHash to complete an attack.<p>I found it surprising that it is possible to rent enough hashing power for many of the smaller currencies, which makes me question the use of PoW for smaller coins.<p>Please note that the attack costs do not include the money you earn in the form of block rewards, so in many cases the costs will actually be substantially lower.
