system token in coin only use
1 ethereum
2 nxt
3 xcp counter party
4 waves
5 maidsafe
if you want ethereum token, myethereum is the best support private key too
I know that Myetherwallet gives you the ability to see and use the tokens but those are based on the ETH blockchain , I'm looking for a wallet that reads the tokens on the bitcoin blockchain , MaidSafe could be an example I guess.
