BTCUSD coming up against major top trend line again

BTCUSD is getting close to the top trend line again

I hope it can break out, however that is just wishful thinking.
We have had weak volume lately making an upwards breakouts difficult.
It is easier for it to bounce off that line and drop down - as it has done three times since May

I dont know where the bottom is, but this line looks like the most likely top in the short term.
