eToro is a social trading broker which is regulated by leading industry entities like Australia's ASIC or the UK FCA. eToro is the latest in a long line of online trading exchanges, but it offers something no other site does: virtual trading. You can practice your skills and see what trades professional investors make before opening an actual position!
It also provides CopyTrader — a feature that lets users "copy" buy/sell orders from other members, so they don't have to wait around for their own trade ideas or try catching those memorable moments when everyone's talking about stocks at once. Lastly, there's a mobile app available if investing while out running errands becomes too much work.
eToro offers access to two platforms, the desktop and mobile app. The former is for more serious traders who want access to trading signals as well as complex features such as an integrated watchlist. It also supports market orders on all supported currencies in addition to Bitcoin (BTC). On top of these basic functions, there's a dynamic but customizable interface that should appeal to more experienced traders.
