Well if you have made yourself familiar with the trading platform using a demo account you can now switch to a real account. I can understand using a demo account doesn’t make you feel like you are trading at all since no actual money is involved.
Real account trading is much different from demo trading as when your funds are actually at stake the trading emotions are completely different . So you can rather do both the things side by side . Invest a few funds (depending on your income) in a real account and see how you are trading. If your’re going good you can continue doing the same and if you feel your strategy is not working you can trade on some demo account with a new strategy to see how it turns out.
