This market does not have the steam to break 10K
Will buy back in when things are making more sense.
Bitches are buying ETH and Bitcoin Cash
BTC dominance is going down hill
A Bear Market could be triggered if BTC goes below 9520 according to one analysts. it has already done that today: Tread carefully and use stop loss if you recently bought in!
When you sit and see BTC go down 450 USD in a day you need to ask yourself WHY? Whales didnt do it is called market sentiment. The whales spiked it 1000 USD in 5 minutes not long ago and caused this mini rally!
Maybe there is not enough steam for the next couple of days or 2-4 weeks. But I wouldn't wait too long to buy back in.
Many guys got burned as they thought Bitcoin doesn't have enough steam to break a certain level. And guess what happened?

Furthermore the dominance index is a pretty bad metric when each week more and more useless coins get listed. This says absolutely nothing about Bitcoin's strengh.
Where I agree with you as that a decline of $400+ in a matter of hours is a short term sign of weakness. But don't forget about the fundamentals who are looking extremely strong and have never been better. So don't become uber pessimistic, because there is absolutely no reason to.
8900-9100 should be a very strong support level imo.
And when you have a look at the weekly chart you'll see we already bounced off from the 50 moving average and got rejected at the 20 moving average. As soon we break through the 20 moving average and stay above it for 2 weeks at least, this could be the sign of a possible next uber bullish rally.
In my opinion you did a wrong decision because if you sold your all holding due to the fluctuation in the price then it is wrong because a little bit up and down will be there in the price, because it depends upon the market cap and people will buy and sell their holdings according to their needs. It will be better to buy bank some bitcoin and hold them for some time.
