Bitcoin & other cryptocurrencies going down. Reason to panic?

If you are new to the Bitcoin Ethereum and other cryptocurrency space you might be in panic right now.
If you are longer in this game, you knew this was going to happen. Especially with these billions of dollars of
new money entering the bitcoin and other cryptocurrency space.

What will happen on the short term with the price of Bitcoin? Will it fall down even more?
And what will happen on the longer term with bitcoin and other cryptocurrencies if you take other factors in to account?

Time to speculate :)
