something I did not understand ... you mean that WYV coins are useless? and that after the block of 315000 the coins that were produced are worthless?
Wyvern was ported to an ERC20 token at block 315000 - all coins mined before that block can be redeemed for ERC20 WYV tokens at
https://redeem.projectwyvern.com. The Wyvern development team does not intend to do anything with the original blockchain past block 315000 (it will not work with the Wyvern Exchange), so I do not expect coins mined past block 315000 to have any value.
