What is the current exchange that everyone is using? I haven't played with altcoins in quite some time.
poloniex.com and you can see that from coinmarketcao's daily volume list. although I personally choose bittrex over it.
but it doesn't matter which one everyone is using you should look at other things such as
how honest they are,
if they are going to run away.
if their platform is even safe.
if they accept you from your country.
will they ask your personal information.
is the platform reliable or does it go down whenever there is a slightly more traffic.
how are the fees.
do they have the coins you want to trade and is the orderbook big or is it thin.
these are the question that you need to think about yourself.
What is the current exchange that everyone is using? I haven't played with altcoins in quite some time.
there are many exchanges today for the cryptos, but the major exchanges are Poloniex, Bittrex, Yobit and C-CEX.
Yobit has a wide list of coins to trade because they never delist a coin unlike the others.
Yes yobit is popular and well known for having vast of undervalued coins. That's why yobit is one of the current top exchange they are being loved by those traders that are into low value of coins. But for me, it will always be a good choice if you will trade with Poloniex and bittrex.
you only thing yobit is popular because they have had lots of signature campaign participants who advertise it day and night and since they get paid inside the exchange account they stay there and have no experience with any good exchange and think yobit is as good as it gets.
