The value keeps on fluctuating, not stable. It's no longer easy for newbies to invest in Bitcoins since the value is too high, only people with a lot of money can do that
It doesn't really matter if you have tons of money or not when it comes to investment. You get what you deserve. If you only invested a small amount of money, you can never expect to have better results with someone that invested a lot more. Unless you invested in a different coin and your coin made a lot better performance, that's not going to happen.
Back then, when the price of bitcoin was just $400, people everywhere are talking about how high is the price of bitcoin. They are saying that they are waiting for the price to go back to $200. The people (even the ones that don't have tons of money) that never listened to that opinion, just carried on, and invested in bitcoins, they have made ridiculous profits by now.
The problem doesn't reside on bitcoin's side, but rather on the investor's. They are too scared to invest on bitcoins. Hence, no profit for them. Like I said, you get what you deserve.
