this site only indicates how much it will cost per hour to sustain the attack. it is unknown how long it could really take for attack to be successful, also as others pointed out - there's no incentive But yes, most of these garbage tokens can be attacked. But it is quite evident to me that eventually people will understand that it is just Bitcoin that they need to follow to keep up to date with the field of cryptocurrencies. Others claim to bring cool concepts and technology but in actuality they don't work or are a messed up very large software project like Ethereum (and tons of projects don't are simply forks with no further development)
