Unless u mention your country & currency, there is no definitive answer to it.

If you just want to exchange currency then use decentralized exchanges, nothing can be more safer then that.

indeed good question ...


the problem with any type of distributed databases that offers buyers/sellers match is the distributed conception itself ...

The exchanges which i am usually trading my altcoins are Yobit, poloniex, bittrex cryptopia liqui, and livecoin . This are some exchanges were i use to trade so i can tell about about it. Because i use to participate in almost all new altcoins bounty programs and were ever they get listed i have to trade in that exchange.

I love using bittrex.
I have no problem with it.
I can say this one is a good and trusted exchange.

So far the most reliable and most trusted exchange site for now is Bittrex, I have no problems using it and it is easy to maneuver around. Before I was into Poloniex though Polo is still a good trading site and I had no problems with them as well but I do have read a lot of negative feedbacks on this site so I opened a Bittrex account too because I was suppose to transfer my coins their but since I had no problems with both trading sites I'm keeping them both but currently more on Bittrex though.

Thanks for the review. I will try go to kraken exchange. because for now I am still in Bittrex exchange and indeed for the moment I have not found a problem with bittrex but in case of bad things come I will try another exchange

none of them!
and they all have the risk of turning into Mt Gox or Cryptsy or a dozen others that ran away. these exchanges are not exactly regulated and they can easily fake anything they want from volumes to prices and to walls to manipulate. of course the effect each of them have on different cryptocurrencies are very different and on different levels but it exists.

among crypto currency exchanges we have to choose among bad and worse. so we choose bad.
if I want to rank them I do it this way:
for bitcoin: Gemeni, Kraken, then bitstamp, bitfinex. (I don't like Gdax much).
for altcoins: bittrex and then cryptopia and then c-cex and after it at the end of the list poloniex.

I'm currently using kraken for bitcoin buying/selling, they're good. for altcoin i would recommended bittrex, kraken has few altcoins too but not as many as bittrex. always remember this, never keep coins on exchanges/use it as a wallet. be safe!

I was going to mention Gemini too. It's one of the few regulated exchanges, and if the big boys ever get into bitcoin, they'll use Gemini over the other exchanges simply because it's not a fly-by-night operation.
