Trading of crypto, stocks, and forex are being done virtually. To avoid confusion here, I assume what you meant about "virtual trading" is practice trading with a digital currency with no value. And real life trading means, engaging into a trading platform with digital currency that has an actual value.
Now, the purpose of practice trading is to let the newbie trader understand the functions, chart, and market movements. But, when you're trading in an actual trading platform, things would obviously be different because there is already a pressure, doubts, and fear that plays along your emotion that will challenge your risk tolerance.
I've said this a thousand times that nothing would ever teach us a good strategy in trading but our own experience.
