I am looking to buy small amounts of different alt currencies, could you guys suggest the two best exchanges for this purpose. The exchange should be reputable, have decent transaction volume and also have a lot of alt currency listed.
Which exchanges, based on the above criteria would you guys suggest.
Thanks
Thing is that there can be huge differences in volumes for the same coin in different exchanges. There may be also a large difference in price between the same coin in different exchanges.
A current one is NAUT - just now was at least 1500 satoshis cheaper in Bittrex than Poloniex. Sometimes this is down to day traders not bothering to get the means to transfer coins between exchanges - NAUT needs a NXT plugin for transfers.
Other disparities are found in market pairs - the price can vary between BTC, LTC, XMR and ETH markets.
Mind you, you need to do the Math and work out the fees etc.
I guess my advice would be to register with as many reasonably high vol exchanges as you can - and don't keep large holdings in any of them if not trading.
