Demo trading allows you to learn. This has been around for a long time, it's very easy you just need an email to register a demo trading account. However there is a problem, when you trade demo you will not have real emotion like when you trade real money, so even that you win in demo, you still lose in real trading. The only way to solve this is you should start with real trading account and put some tiny money in it, start trading and learning.
it allows everyone to learn but we must remember if the demo account is not even showing what was the real condition in the market. It's better just try to spend a few dollars to be a practice funds to make people can adapt with the situation in the crypto market. That will bring a lot of lesson than demo account.
