Of course, Bitcoin can easily crash means when the price fall, As a trader, you should already know that one day the coin definitely go down so it is always advisable to have a Plan B. And secondly you don’t need to invest all you have just invest what you can afford or even if a big amount, don’t take all your money and invest in bitcoin, because definitely not good idea, you can just decide to be taking certain amount from your payment monthly or weekly and invest on bitcoin, because you should already know that it goes up and down.
Bitcoin is not going to crash, so you better remove that thought from your mind. Let me ask you what is going to make bitcoin crash? Bitcoin is not a centralized coin that means it's the people that owns bitcoin. Many people have been enslaved with this idea that bitcoin was going to crash many years ago yet bitcoin is gradually approaching 2 decades. Thoughts like this are the reasons why many people has missed out on bitcoin from the early stage. It surprise me that people like you are still habouring the thoughts that bitcoin will crash. I only have one thing to tell you and that is "You guys will wait forever".
