Estimated coin impact
Scores are not price-change percentages. High impact means a score of +70 or more, or -70 or less.
Impact unavailable
Regular reminder: A key property of a blockchain is that even a 51% attack *cannot make an invalid block valid*. This means even 51% of validators colluding (or hit by a software bug) cannot steal your assets. However, this property does not carry over if you start trusting your validator set to do other things, that the chain does not have control over - at that point, 51% of validators can collude and give a wrong answer, and you don't have any recourse.
