I'm not new to cryptos and not new to trading either. I've been using several platforms, but I landed at my two favorites and if it goes on this way, I'll stay with these.
Etoro
Etoro is not a platform, which people have in mind when trading cryptos. Etoro is an old-school trading platform in the sense of cryptos. It only supports the "big" coins.
But there is a slight advantage using etoro at the beginning. You don't need to set up a wallet and you can deposit with multiple methods (paypal, skrill, card, etc.).
On Etoro you have the possibility to learn how to trade by following more experienced traders and see how they do it. When they open or closed positions and you can get into discussions with them asking why they did it.
And even further, you can copy someone, whose trading style is favorable for you. In this case, you get to open and close positions automagically. If the guy you copy makes money, you do the same.
Binance
One step further. Binance is a more advanced platform compared to Etoro. It doesn't have the social features, the following and copying part. But it lists way more cryptocurrencies. So if you are into crypto (why else would you be here at steem? :)), binance is a good place to be at.
Registration used to be closed, but they just reopened it this morning.
Binance lists almost every crypto. I have an account at Bittrex, Poloniex, etc, but Binance is way better, not to mention it has a very clean Android app, so I can use it on my phone. Other crypto only trading platforms don't have this extra.
On Binance you have to decide what is your base currency. BNB, BTC, ETH or USD.
The most pairs and the most common base currency is BTC, but using Binance's BNB, you get better rates. So it's up to you to decide which way to trade.
Which platforms do you use? Why did you decide so?
