Thanks for the link. I read it, not sure if I understand it correctly:
1. get the Chrome WavesLiteApp and create an account in the Waves Lite wallet
2. buy some Waves maybe 0.1 e.g. with Bitcoin at shapeshift.io because you need Waves to buy anything within the Waves Lite wallet for the DEX trading fees
3. transfer the Waves to your Waves address from your Waves Lite account
4. transfer Bitcoins to your Bitcoin address of your Waves Lite account
5. buy some Wagerr coins with the Waves DEX token number "8t8DM...5dsw"
I made the account in the Wave lite wallet. IT seems like there's a mini exchange within the wallet where trading is going on and I could see WGR/BTC pairing there. But am confused about instructions above where in (2) it says to first buy some Waves through BTC in order to buy Wagerr with Waves.
Also, what is the use of (4) if I already have to spend all BTCs to first buy Wavers?
