Thanks Guys <3 just to clear some things it needs some hell of a time by this way too yeah ? 
Well it depends how fast ViaBtc is to mine a block
Yesterday, it took like max 2hours for TX to be confirmed using their tool : https://pool.viabtc.com/tools/txaccelerator/
Here you can see it's been a while no ViaBtc block was : https://blockchain.info/en/blocks
