I guess the same amount of transactions as Etherium can since Agate is on Etherium blockchain.
You must be right, but what will happen when ETH switches to POS, will that affect Agate?
Agate is also switching to their own POS blockchain,so that wont affect Agate at all,and i dont Ethereum is few years away from POS.
What does that switching to POS blockchain mean? Will that affect our tokens?
It just means that Agate will migrate from ETH blockchain to it's own blockchain and you will have to swap you AGT erc-20 tokens for AGT coins on Agate blockchain.
When do you think that we expect Agate's own blockchain to be ready?
Well, according to roadmap Agate main net should be up and running pretty soon.In Q1 2019 already.So shortly after that we can expect a swap to be initiated.
