there is a lot of resistance above $10,000 and just because some lines and wedges that the chart has point to a certain price it doesn't mean it will go there.
first it has to go below $12k again and be able to hold it there, there has not been many left in the market to sell their coins and unless something forces them to, i don't see them selling either.
a price dump for bitcoin could really help bitcoins tx costs, and make it a popular cryptocurrency again
no it won't.
if the speculation in that chart you shared comes true, it means a lot of sells which will also trigger a lot of buys eventually too. and that much selling and buying means a huge number of transactions and that will obviously lead to higher fees.
