How long have you been here?

It's always easy talking afterwards, but if fundamentally nothing really has changed in the last years, why should it not do what it has been doing since its very first exchange listing? The retail side of it will always be a major contributor to bull and bear runs, and as long as they contribute to most of the activity in this space, the market will keep bouncing up and down like crazy.

Another aspect heavily contributing to Bitcoin tanking hard during bear markets, is that altcoin markets don't provide sufficient liquidity to their traders to cash out. What happens is that they cash out to Bitcoin and dump their coins on Bitcoin's fiat markets. We have to swallow dumps from two sides of an industry and that won't change any time soon.
