I still have 'INS referral tokens' What can I do with them?

so they'll be added to my total INS tokens?

You'll be able to see KYC verification results in Profile, just instead of KYC button there will be "KYC Passed".
You’ll be also informed by email.
Update is coming up within few days (up to 7 days).
Until that time you’ll see “click here to fill kyc, do it now”, that's normal.
There’s no need to fill it more than once.

INS token as already created in MEW, so I don't think it's necessary

binance and bittrex. follow their updates 😉

so in short bounty participants need to do the KYC? and how will this be done? is this necessary? i think this is only must be done for the token sale participants or the investors.

The telegram bounty channel contained information that now the waiting for the decision of lawyers, and, probably, bounty participants must pass KYC verification. There is still no final solution.

Team has done a lot of hardwork before the ICO and last they reached the hard cap with specified time only and made some partnership with other companies.

What happens if I do not specify an ERC-20 wallet by the 31st of December? I've been away from home.
