As per the official Waltonchain Twitter page: https://twitter.com/Waltonchain_EN?lang=en
There is an airdrop for all WTC holders on 21st March 2018.
"At 00:00:00 UTC+8 on March 21, 2018, we will take a snapshot of wallet addresses of all the WTC holders. Those with the sufficient amount of WTC (i.e. ≥50) in the wallet at this moment will receive 4 FREC for every 1 WTC."
My Etherwallet simple setup Instructions:
So you need to store your WTC in a wallet where you hold the private key. The wallets they recommend are MyEtherWallet or Imtoken Wallets.
Don't share your private key with anyone. Do the transfer on a trusted and safe computer.
The snapshot of the WTC blockchain is on the 21st so you probably should have your WTC in your private wallet 24h before to be safe.
Go Walton!
========================================================
*Personal Opinion: Given the low price of approx 2c per FREC its probably easier just to buy $20 dollars worth. There will be fee's sending to your wallet then fee's when selling on an exchange etc. Eg 100 WTC gets you 400 FREC which you could buy for approx $7.20. FREC on coinegg are 0.018 USD each as at March 18.
