It's hard to predict the specific value of Bitcoin as it fluctuates rapidly everyday. This is the same for most cyptocurrencies though and it depends on the investors and whether or not they will want to invest in them.
This is why companies like Baanx and Binance called cryptobanks, let you insure/save/secure your cryptocurrencies that you have bought instead of worrying about it's fluctuating price.
It had dropped below $6000 last week but the high of today was $6500 so I don't really think it's that shocking of a drop. Have a read of this blog which explains it in really good detail. Worth a read
As an ambassador for Baanx, I think making videos on cryptocurrency sphere is a great way to keep the public updated. We also do this on our website if you are interested.
