I think, each person can become a successful trader. So, i ask about platforms which is simple to use
I think polonox is very simple and trusted. Trader can easily trade here. It is biggest Platform.
Is it for single asset?
Maybe he meant Poloniex? If you're a beginner I wouldn't suggest this, hence it's big platform but its interface is quite confusing for beginners. You can find more pairings in the site otherwise DYOR first before using it.
