In my point of view. As a new currency bitcoin still has low liquidity so even if someone have 5000 or 10000 btc then that person can  influence bitcoin market. I got so many knowledge and information from legendary members here that help me to do calculation about bullish market trend, highest and lowest price level possibility. Now I tend to gain profit rather than loss. I think the key is we have to keep on learning. Now I learning about traders behaviour, I think traders are the biggest factor that makes bitcoin market so volatile.
