As I understand, snapshot has already occurred on the block #1894000.
And when will the MTR tokens send to the NXT wallet? Tokens will be blocked until the miners produce another 200 million MTR? When and what exchanges to wait? Also it is not clear yet what will be the interaction with Ethereum Classic.
1) MTR tokens will be given you on Metro blockchain not NXT.
2) Tokens will be unlocked in equal portions each mined block. All initial tokens will be unbloked when the miners produce another
400 million MTR. Miner block reward 2,000.
3) After blockchain start we will trade MTR on NXT blockchain. Then we think about other exchanges.
4) There are a lot of quasi DEX based on bitshares for example. But all cryptocurrency you send on that exchanges stored by their owner. So they can lost or stole them. When we talk about DEX we mean that all cryptocurrencies will be stored also decentralized. We designed Metro that we can not lost or stole deposited cryptocurrencies. We will implement transition smart contracts on each blockchain. Firs blockchains we implement such contracts will be Ethereum and Ethereum Classic.
