I think people are misunderstanding what w00tcoin is actually for.
It won't be replacing 1337 coin, its basically a coin to be introduced to decrease the amount of 1337 coin going around. 100 1337 coin will be spent for 1 w00t coin.
yobit 1337 wallet in maintain mode for a long time.is that the reason for price hike or swap
Could be. there to lazy to update there wallet if you go back a few pages velvet posted some details about his contact with yobit with dates and everything until now no response from the yobit dev.
So it's best to avoid yobit for trading 1337 (and other coins to but thats a personal thing)
