oh nice i will go and try. Is there any exchanges that i can buy with cash and not with bitcoin? or is this the only one available.
Kraken is one of the places you can buy/sell Monero directly for USD or EUR (also for Bitcoin).
You could ask in Monero thread, there may be more such exchanges / services.
I don't know about ZCoin, but it's much newer and not as popular at exchanges (personal feeling).
The biggest altcoin exchanges are Poloniex and Bittrex, that's where you can trade altcoins for Bitcoin. Poloniex has a ton of complains lately (although I encountered no problems) and may not have ZCoin, so Bittrex is a good place to acquire ZCoin.
