How do I know if I was involved in your airdrop?

Which exchanges will support this hard fork?

The project has really impressive roadmap and reliable devs, I think we will see this coin on the Moon in this year.

Is there any bounty or maybe airdrop?

I guess, the safest one is Ledger Nano S. You can order it on the official website:

It's hard to say which one is more risky... I think they both are very risky, but gambling requires more special skills and luck than trading.
