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?
Yes, if it takes too long, send your bitcoins with a higher fee and you won't have a problem. I know it sucks but that's how it is now.
You can check the current fees here:
https://bitcoinfees.21.co/If you send your bitcoins and pay 201-220 bytes/satoshi as a fee, they will get through almost instantly. These numbers can get higher or lower depending on the current situation, so always check the website i wrote above before sending anything.
