I have been making several big BTC withdraws from exchanges today all of them were completely confirmed within an hour, what it going on here?
Update from Hashflare:
Update 22.12.2017 09:15 UTC: BTC withdrawals are enabled in test mode, with the minimum withdrawal amount set to 0.1 BTC. Bitcoin network fee at the moment is 0.0022 BTC. We are working on changing the method of creating transactions to batches of multiple withdrawals, to reduce the time it takes withdrawals to reach the destination wallets and to reduce the network fee for our customers. We do not recommend withdrawing while the network fee is this high. What a brilliant idea from them, creating batches of transactions...

So now the fee is high and if it goes back to 0.001 they will celebrate themselves for it. Let's see what the "new minimum withdrawal amount" will be this time.
