I would like to understand the main reason behind the bitcoin dip/crash (whatever it may be). Currently BTC is trading at 12.5K on preev.com, and I am beginning to become scared as to what the near future may hold for bitcoin.
Hold or sell, what do you think?
PS: Please don't just spam this thread with:"Sell now, it will crash" or "Don't worry, it will go up". Base your points on facts that drive the discussion forward, not just general terms that have been already written down many times before.
You can consider the BCH bull run as one of the reasons. But they also got dumped today with the majority of the alts. But hey, we all wanted a fair correction in the price, shouldn't we be happy so that we can buy more of bitcoin?

I'd definitely suggest you to hold, you could have sold and could have bought back immediately to gain some nice profit when the price was around 16-18k but don't do that now, it's risky. Support levels are firmly formed.
Is this a Bitcoin crash? Or is it a crypto crash too? Is it just the holiday season or something else? We can also see on coinmarketcap.com that in essence, almost ALL alt-coins are also down by a similar amount in %.

This should answer your question. Basically most of the time when bitcoin crashes most of the alts follow. As per the image, 80% of the alts have crashed a few alts have gained here and there. Two major gains were in the XRP and KMD markets. Everywhere else it's not a good time to sell, but rather a good time to buy if you're a trader.
But bruh XRP❤❤❤. Sorry for the off topic and the spam here though.
