Thanks for the reply, lizardbtc.

Viabtc doesn't take any requests atm. Trying since few days. Will look into the other options, thanks.

I'm using mycellium wallet and it has the great feature to bump the transaction fee. But somehow it's crashing every time I try. Looks like it only works for the transactions I sent myself.

If there is someone around who could help getting it through it would be very much appreciated.

I check the unconfirmed transactions every day but doesn't help me if I get pushed back all the time. Have seen a bunch of transactions with same or lower fee, but never seen it going over such an insane time frame.

If there is a chance that a transaction goes back, Im wondering how payment processor bitpay deals with it. Every payment even with zero fee gets accepted right away and digital good or orders get processed right away. So I thought that possibility of transaction going back can't happen often in total.
