May somebody here help me finding an answer on my question?

Is it save to buy BLZ on IDEX?

After the information by WanChain that those WAN that you can buy on ED will not be able to swap to "the Wan-Chain" later this year, I wonder if there is any problem like this (or similar) with the BLZ one may buy on IDEX?

https://idex.market/eth/blz Linked BLZ-contract: https://etherscan.io/address/0x5732046a883704404f284ce41ffadd5b007fd668

note: I know it´s available on Binance, too, but the question is meant for IDEX only.
