Thanks for notifying us. Because there is currently a high number of typo-related PRs across cryptocurrency-related repositories, and because I suspect that this is an effort to stake a claim at tokens rewarded to project contributors (like this one, for example), I will incorporate the changes you suggest in a new commit and will give you a shout-out in the next changelog.
