Right. They have to burn them. That way each coin receives a greater percentage of the dividend. So it's good for bagholders, which is the whole point of the coin.
Yep, but we can't assume burning them will increase the valuation enough to make up for the 25 btc (or however much they'd spend) buying the coins in the first place. Simply reducing the number of coins should increase the valuation... but who knows how that could work out.
XC coin is reduced 50% of coins in pow phase. its work. value go up.
