I think this will be a good website for newbies to learn and practice trading. I had my first trade in coinex when I was new and it was terrible I lost some money since I thought I can trade because I've read some and watched somw lessons on trading. This will really be helpful to simulate and be familiar in trading.
This is useful, but won't help much since actual experience is gained by actually trading. Learning strategies and perfecting them through real world usage along with usage of bots is the primary way for anyone to learn trading in such a volatile environment.
I think this will be more or less like live trading too, because they work with the real time data from real trade, the only difference would be that it is a demo account, where in they are being given demo trading coin, and whatever they practice in here will be same as what they practice out there in the real world.
When I started my own trade, it was a dummy trading platform that really trained me, which I was even able to develop some strategies to perform the real life trade, although that was forex trading, but there is no difference between forex trading and crypto trading that much, just that one is more volatile than the others.
