Well I think getting listed on Bittrex or Yobit would also help Piggycoin out quite a bit because they seem to have good action on lower valued coins like PIGGY and things
PIGGY was listed on Bittrex in the past and delisted -- Unfortunately it costs a lot to get back on there.
Yobit were having some problems with updating wallets and adding the coins that coin teams have paid to add, a few months ago. I haven't kept track of them since. Let's give them time to sort themselves out.
Why not give your custom to Cryptopia? :8]
