Yes my some transaction are pending because of low fees and also i tried to send my another bitcoin wallet address using low transaction fees its after week showing pending . So it has to be change otherwise there will be a tough days
I can make a good advice to you if you already dont know about this service:never send bitcoin with low miner's fee,it will get stuck on next "available" block.That's why always use recommended fees when you make transaction. If transaction get stucked on blockchain just try free transaction accelerator services like viabtc to solve this problem.Always check count of unconfirmed transaction on blockchain.
