Exchanges

BTC-e.com

There are a bunch of them.  You should do research on a bunch of the big ones and see which looks safest to you.  For instance I know BTC-e has been around but it's not in an English speaking country and I always have trouble with what they're trying to communicate so I worry that one will go belly up at some point.

Biggest exchanges now is all more or less stable, noone is so horrible like gox was.

Yes, i hear about mtgox fail. But not every exchange will repeat gox story. I hope it.

Hi, can someone tell me about exchanges of crypto currency (btc+altcoins)?  

I suggest bittrex. By far they have the most altcoins and the volume is highest among the exchange site..

I haven't heard of any local exchanges there, but you can use big global exchanges like bitstamp and btc-e, or arrange some p2p trades with localbitcoins.

For paypal, you can use Virwox https://www.virwox.com/. The fee is pretty high, but it works.

For USD, you mean wire transfers? If so, almost all exchanges accept USD wire transfers.

for trade altcoins  i use bittrex.com and poloniex, i think most of people use it
and for BTC, Altcoin and Fiat exchanges site, I recommend BTC-e.com

[btcguys]

I suggest you use Bitstamp.net it is trustworthy and their UI is decent plus they have customer support that will answer your questions within 24-48 hours and speak ENGLISH instead of translators.

But never make a mistake of storing BTC on an exchange.

Here is a guide to help new users verify authenticity of file download from internet, installing offline wallet and broadcasting transactions online without ever revealing private key(s) with pictures:

it is best practice to read about common frauds/scams related to BTC on bitcointalk before getting into BTC

Altcoins bittrex and mintpal. For new coins also c-cex, for SEPA transfers kraken.com.

Poloniex always adds the new coins faster than most exchanges and has nice volume.

Watch out with them. i lost lots of money on Mt Gox and coinmartket in the past. You are warned.

For altcoin exchanges, I believe Cryptsy is the biggest and most popular one out there.
For bitcoin exchanges, you may try Btc-e, Bitstamp, Coinbase (if you are in US) and Localbitcoins (if you want to do it p2p).

[LorettaAndrews]

Have you tried Poloniex?
It's fast and easy to use, recently the have added the new stellar coin.

poloniex don't support btc/usd
just altcoin

An exchange is where you exchange a currency for another currency.

OP wants to know about both bitcoin and altcoin exchanges.

As an altcoin exchange, Poloniex is not bad at all IMHO.

BTC-E is located in russia i think. So it's kinda risky to trade there.

Owners say its located in bulgaria as for being risky if i was to choose between a new exchange and btc-e i would rather go for btc-e as its been around since 2011.

I also use it and i have never had issues with them, so far.

Yeah, owned by Russians, located in Bulgaria, business banks in Cyprus or something...shady guys if you ask me

And unlike Bitstamp and the dead Mtgox, no one ever know who the owners of btc-e are.
So yup, it is shady but it is still working well at this moment.

A friend of mine "forced" me to use TheRockTrading as my first online wallet and exchange but I don't think that it's one of the most trusted here.
