so if i want sent veil to exchanger can i sent with base coin or should it convert to zerocoin ?
According to Telegram it was a POS bug which was used by some users, so probably all staking rewards was earned by them.
Crikey, whats next.
this is false, the vast majority of PoS rewards were won by 10 denomination zerocoins, those were unaffected. The issue was that higher denomination efficiency parameters were not enforced by consensus, so people could gain an advantage when staking higher denominations. The soft fork has made it so that the parameters are enforced network wide.
