A2A stands for Any2Any. explanation in image below:
So for those who have STE tokens and thus will receive dividend distribution:
30% of your monthly dividend amount payout will be in ETH.
70% of your monthly dividend amount payout will be in A2A.
You can obviously trade your A2A tokens for other tokens on the STeX EXCHANGE, and I've heard rumors that in the future you will be able to have a setting where you can set all incoming A2A to be traded automatically into one or more tokens of your choice. So for example if it's the first monday of the new month and it's time for my dividend payout partly paid in A2A - I can set it so that STeX EXCHANGE automatically trades that A2A into IOTA or whatever other token I'd want to accumulate, so that I don't have to do that manually every time. Then again, maybe just hodling A2A is the way to go - I mean just look at the value of BNB (Binance Coin.)
