To be honest, the cryptocurrency world is rather difficult in "accurately" predicting the trend of its prices. With its high volatility, the price may either increase/decrease without given notice. In addition to it, unlike in stocks, the trading aspect happens every minute as compared to stocks where the trading happens on a certain time.
If you want to start investing in cryptocurrency, then treat it as a normal investment. But you have to regularly check its price on the market. I know lots of people who accumulated profit even in short-term investment due to sudden spikes in its price.
As a general rule also, only invest what you can afford and lose at the same time. Be wary of current events since majority of the news affect the price of BTC in the market. Good luck on your investment, OP!
The Cryptocurrency world is open for everyone that's true but that doesn't mean anyone with zero knowledge about this technology can jump in and make huge profit.
You need to be well equipped with volatility, speculations and price volatility to deal with bitcoin.
You can earn profits in short term occasionally, for long-term profits you need to have an investment strategy that is spanned over a period of time. Short term investment doesn't work in long term.
