The article criticises Coinbase and praises Poloniex for having zero fees.
The only problem with this: Coinbase is a solid exchange and Poloniex is crap.
The move from Poloniex to have zero fees is similar to what Cryptsy did before they did a runner. Zero trading fees (to encourage volume) and high withdrawal fees (to discourage withdrawals and make a profit from those who do take their money out).
It's not a good sign. You should always ask yourself how these exchanges make profits. Some are upfront by charging fees. Others are dodgier and are using your coins to trade while trying to discourage you from withdrawing.
that is pretty much makes sense.
could not agree more with you. there is a lot of problem with poloniex such as freezing user's account without valid reasons , a sudden maintenance, extremely poor support and manymore! that is why they have zero fee as they lack of professionalsm .
better to have some fee in an exchange but gives you a security rather than zero fee but you will feel insecure the whole time.
there is money , there is quality. don't blame if you get charged as it is for providing a better service , that's all.
