I believe $5,000. After I witness the price movement this year so far, I already think we will not going to go down again.
What we will witness is just some minor correction and we will be trading at least $10,000 before the end of the year.
In a few weeks ago the market has been showing that the price of bitcoin will up again and agree the correction area will touch the lower price around $7800. Most likely bitcoin price will up again and will find another resistent maybe $9500 is the purpose at this time. So, I a bit agree if $5000 is the lower price that won't be seen again on this year. However, for 2020 I still doubt that the price will meet a crash such as 2018 ago, if the crash comes then $5000 will be seen again.
$5,000 sounds really low for a crash after the new bull run, Bitcoin always keeps increasing in the long run, and new bottoms are higher that past ATH's - if this pattern would hold, the bottom of 2020 or 2021 - whenever a new bear market will happen, will be at around $12,000-15,000. But there's always the risk that the market will stop behaving like that, and that we'll indeed be dropping back to the old prices, so seeing $5,000 again can happen under that condition.
