Issues affecting Htmlcoin include:

- A lack of a 2017 audit of the HTML5 to HTML swap of the 80 billion premined HTML.

- A supply discrepancy and lack of transparency regarding a manually generated special block reward of ~13 billion HTML on block 106,000.

- The halvening event is set to an incorrect block which sets the max supply of HTML tens of billions higher than listed in the whitepaper.
