Since the cryptocurrency markets are open every hour, every day of the year, you can commit to day trading how often you like. Cryptocurrency can operate via a decentralized blockchain, so you can avoid the middleman to pay no fees from or manage your money.
You'll want to understand both fundamental and technical analysis. Most day traders use price action, chart patterns, and other indicators to trade. You'll also want to watch for fundamental news to make informed decisions about how these trends might affect the price of a digital asset. Like with any other asset class, crypto prices are volatile, so being disciplined is key.
