The markets are getting worse and worse as the days are getting worse. We can say that Etherum is experiencing a much more radical decline. But most importantly, how will the Altcoins recover after this hour.
Most (nearly all) altcoins will not recover. The ecosystem cannot sustain them.
The market is in a bear phase, and will be for the rest of 2018 at least.
But you know don't you, that if I was ever to sell a big portion of my bitcoin, the market would take an amazing turn upwards and go to new all-time-highs, and I would never want to buy back in. It's the rule of perfectly bad market timing. And I would be able to brag that I sold at the exact bottom. That is why I will hold regardless of where the price goes.
