With the latest developments of Bitcoin Gold and Verge falling victim to the famous 51% attack I would like to share how much it actually costs to take over a specific network (according to this article less than 500$ for $EMC)

Two shitcoins dying, nothing to do with BTC.

Let me know if you think these figures are accurate as I read 1 to 2 billion for BTC.

Of course, the numbers are a bit pulled out of you know what...
From their own website:

How is the attack cost calculated?
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 the attack cost does not include the block rewards that the miner will receive for mining. In some cases this can be quite significant, and reduce the attack cost by up to 80%.

The problem with their assumption related to BTC is the source of the hashing power.
Nobody is going to rent you the equivalent of 1 million S9 in hashing for 1 hour Grin

.
And I don't see the billions you mention on the website, they claim half a million for one hour or around 12 millions for 24h.

But again, not going to happen, it like renting your tractor to a kid that wants to drive to your strawberry fields.
