The last day for the 1:1 swap ratio for HTML:HTML5 is February 12, 2018. This is true regardless of where or how the HTML5 coins are held. As everyone, including Yobit users, have had ample time to swap their coins, there will not be any exceptions to the swap ratio timeframes.
If you have coins currently stuck onYobit due to a failed withdrawal, you must arrange a solution withYobit. The HTMLCOIN Foundation does not and cannot control Yobits systems. If you have coins there and you havent yet withdrawn them, you can swap, manually, using a Yobicode.
To swap HTML5 from Yobit manually using a Yobicode, please contact me cgarrett@htmlcoin.team directly. If you have HTML5 coins in a wallet you control, please swap using the swap form on htmlcoin.com.
The swap ratios Will apply depending on when you send the valid Yobicode, so do not delay in taking care of this.
