There is no need to increase the fee to 100 sats/vbyte. As the guys posted above, use the viabtc service to accelerate your transaction. All you need to do is go to this service at the beginning of each hour and insert the hash of your transaction. Just be aware that there is an increased demand for this service due to the huge number of unconfirmed transactions in the BTC network at the moment. This means that the hourly limit of transactions on this service ends empty in about 3-5 minutes. By the way, if you send a hash to this service, your transaction will likely be confirmed within a few hours, given that viabtc has mined 13 blocks for the last 24 hours.
