The fees are high and nobody wants to pay more,even if the price rises. This is nothing besides human greed,they only want their income to rise,not their expenses. One of the main reasons for the huge amount is that people are willing to sell,since the price has hit ATH,they are moving their coins from wallet to wallet,and two they don't want to pay high fees and are persistent about it. They don't even know to accelerate their transaction and are spamming about accelerating their tx wherever possible. The price of btc is not dropping because of support not 'cause of tx fee,is it? Agreed to some point that the unconfirmed tx can cause a delay for people to dump but otherwise this is just a minute reason for the price not dropping. Plus,miners are only in favor of high fee transactions and more priority is given to it,no matter what the amount is.
