Issues affecting Htmlcoin include:

- Lack of 2017 audit of the HTML5 to HTML swap of the 79.8 billion premined HTML over the first 798 blocks

- 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.
