One more thing, you should be a risk taker person because everything in crypto is risky either long term investment or trading. Bitcoins volatility is the key to earn huge profit but if you are afraid to risk then stay away from this investment.
Accepting its nature of being volatile will teach you many things. As you learn how to deal with it, you'll eventually learn that such volatility will really give you that high potential profit but as well as losing. But forget about losing if you're long term on it, you don't have to deal with that much pressure that you see in the market as long as you're maintaining yourself cool as you hold it. It's been seen and done by many and the true potential of bitcoin is there if you manage to deal whenever it's truly volatile.
