Half the truth is a whole lie... owners of HTML5 (
the old coin) can swap them for HTML (1:1) (later it will be 1:2) just like you mentioned. The only HTML5 coins are on YOBIT, and in some old wallets.
The HTML coin on Bluetrade, TradeSatoshi and CryptoBridge are the new coins (html5 swapped to html)
So, if you don't know what you are talking about, it's better not to write such nonsense about the rebranded HTMLcoin as being a russian roulette...
If you're really smart, you yet had bought lots of this coin.
For the record: go to coinmarketcap.com and see for yourself HTML5 and HTML are 2 different coins!!
