When the price is over $1200, a fall of $100 is almost nothing.
It highly depends. If you just have 0.1BTC then such a decrease in price won't impact you, but if you have thousands of coins, then it's completely different.
It's well known that the more you own, the more you potentially lose. In the latter case an 8% decrease results in your coins losing hundreds of thousands of $ in value. Definitely not what I consider to be *almost nothing*.
This is true and the impact will be much bigger if you invest a lot in the Bitcoin then when you do it with less like.
But if you look how things are going with the price of the Bitcoin. I don't think that you will lose a lot of money. At least i hope you don't lose a lot of money.
