High profit high risk
Investing in bitcoin is good, yet its risky,why? If you invest as of today you are not sure if it will pump nor dump anytime, as what happened on someone i know, they invested last last day and bitcoin dumps, they lose their money because they panic to sell immediately their bitcoin. if you really want to earn profit, dont invest now, one day will come that it will dump and we can invest and then wait for it to be back on top.
Yea, yeah, sure there will be price corrections. The price correction actually just happened and the price hasn't come back up, yet you're still saying the price is still high. Which price is "low"? When we were at a lower rate (e.g. 700$, 600$) people are all saying the price is still high yet today we all wish we could buy at that price. One thing, the price of bitcoin will never go down as low as you'd want. It's much better that you buy now while the price is still lower than the peak.
Your friend just sucks at trading. That's all. He's impatient. If he waited long enough, he could have sold some at $2500 just like the rest of us.
Go on and wait for your "low" price and be like:
It is now or never, these might be the last time you will be seeing bitcoin at $2000. These will be the least price you will be seeing these days. If you want to wait for another dump, you can, you can wait for years and it's price will still continue to rise.
