This information is really very useful and interesting.  And thank you very much.  it's over, I was looking for good trading simulators, so that using my tablet, the android operating system, I could usefully spend my free time far from the computer and learn how.  at first I wanted to use the demo version of Bitsgap, but it will most likely be very useful for a computer user, because the Android system does not read it properly.  If you take altcoinfantasy for example, then this is a kind of game that I could not understand.  At least I did not try too hard because I did not like the interface itself.  But coinmarketGame is more or less suitable for a person who does not understand anything at all in trading.  I had virtual $ 20,000 on my balance.  I bought a Cardano coin for $ 19980 and after an hour and a half, there was already $ 20,850 on my balance.  I also bought iota and stellar for virtual funds, but only with a smaller volume, but Cardano gave me the best result.  And in the end, I was surprised that I earned $ 850 for a half.  But something, I too doubt that when investing real money on some exchange, I will get the same results.
