Here are some of the questions that still remain unanswered by the creators of ION:

What are the addresses for bounty and other team wallets?
How many masternodes (aka magical coin shitters) does the Ionomy team own?
What are the burn addresses for all XPY that got exchanged into ION at an 8:1 rate?
What are the addresses for all the BTC collected during the ICO?
How exactly will the team work around Google's and Apple's rules prohibiting the use of third-party payment methods in mobile games?
Can we see valid proof for Ionomy being a registered company in Singapore (not some other company under a totally different name)?

As long as these questions remain unanswered, an investment is extremely risky because Ionomy is most likely a scam.
