Any idea why BTC confirmation taking days to confirm?
Sometime BTC get refunded to Sender....Should we use high fee like advance option for send BTC?
if i want to send 1500$ BTC then how much network Fee should i use to make BTC confirmation fast?
That's a common problem from last year when bitcoin has reached higher price maybe around more than $800, and this month bitcoin reach another ATH over $1800 per bitcoin. But, not only the price reach ATH, unconfirmed transaction reach ATH as well.
I'm not an expert in this case, but to generate 1 block included into blockchain need some (various) time and Max size is 1Mb. I don't know whether miners process those transactions slowly or block size cannot afford so many transactions which delay our transactions.
