For my suggestion since alternative means of payment is temporary you can still leave your campaign in the service section then your participants can pm you their alternative address for payments but still those addresses can remain hidden in the spreadsheet maybe only their btc address can be public. In every week you will give the values in BTC on spreadsheet while you send them the equivalent in their chosen alternatives of payment to their address. This is just my contribution to remain all your campaign in service sections.
This suggestion is deceitful and to what end? Is it necessary to begin play a hide and seek game in an obvious situation of skyrocketed bitcoin transaction fees?
The high fees won't last forever so during this periods, that's a scarify we have to give. Staying with Bitcoin in this hard times is a scarify worth all the old times that the fees were low. Switching to a different coin, give that coin utility instead of Bitcoin so if they're not paying in Bitcoin then the projects don't deserve the publicity they're getting from launchings their campaign on the Bitcoin service board.
Well, I think I understand the premise you are coming from. This is a bitcoin problem and switching to altcoins payment means an unsaid failure of bitcoin. It means bitcoin is unable to deliver the promise of multiple payments with low fee.
If we move to altcoins payment, believe me that it will be in the history that in bitcointalk forum, bitcoin payment failed and they switched to so so alt coin.
From the side of Hhampuz my manager. Moving a thread that has got much exposure in the bitcoin service board it the altcoins board will be a big distraction. I think paying a moderate fee and even if it takes a few days to confirm is fine or you can consider bi weekly payment.
