As far as bitcoin market is concern, I haven't seen fluctuations in recent months, it been quite stable. However, you have to understand that the market is based on speculation, so you will definitely see wild fluctuations from time to time. As others have said, high volatility is a friend of every traders, why? Because its a chance that anyone is waiting for, to jump in while the price is down and then wait for the next bull run to happen. Regarding if this is the right time to investment, honestly, well we have seen the price bottom at $5800-$5900, and at the current price, we're not far from the last bottom so definitely this is still a good buying point.
