[The real bull run has not started yet. Bitcoin is stable between 10,000$ to 12000$ and we are again in the accumulation phase. Once we would have enough accumulation of bitcoin then we might see another pump of bitcoin which will take bitcoin above 15K.
I think bull run already is happening. Look at how the price surge from starting this 2019 up to the present. Bitcoin had been on $3k + then it is on $11k plus now so what do you call this trend? I can't call this a bear market nor it is going sideways. If we look at the chart it recorded several higher highs and lower high << a sign of Bitcoin bull market.
For bitcoin yes its only temporary, looking back how the btc progress this year we can say even the price plunge to $8k-$9k its still good enough since we started at $3k in the first quarter thus dont think this downtrend as negative.
For altcoins unfortunately some of these coins will remain in their current status so it might not temporary, if they cant manage to increase then it will stay at the bottom unless there's a big news that can affect their price.
I guess both uptrend and downtrend is temporary because as we can see, they are performing a cycle. Price fluctuation is kinda crazy in Bitcoin market. Depends on the market sentiment we can see several changes from uptrend to downtrend, sideways then vice versa. And I think this is just normal.
