Idena mining reward per day is 6 idena, will the reward be any less than now ? Will Idena be able to list on major exchanges?
There is fixed 51840 DNA per day per all nodes. So more nodes = lower rewards for each node.

You can buy/sell IDENA on Qtrade - quite good exchange registered in US. Vitex and huobi. In terms of major exchanges - there are rumors (rumors only) about huobi listing. We are close to lauch of ETH bridge that will allow idena to be listed on all ETH dexes.
Ijust hope that rumors true i mean if you look at ETH Fee Idena could be the next Smart Chain or Tron Network
and mining reward getting low while the price still stable ~200 Satoshi i just hope after listing on major exchange like BInance the price will pump and USDT change add more network to Idena
