Viabtc might no longer be an option, and if your transaction is opted to RBF, you prolly should use it and replace your initial transaction with a new one, but this time check the mempool and use a good fee rate. Transaction fees have somewhat dropped, at least it is not as high as it was in previous weeks, so it is better to take this advantage, than waiting, only to see it rise so high again.
I don't think the bots are the problem, viabtc prolly wants to reduce the number of transactions they include in their block that pays a low fee rate, especially now that fee rate is high, and with all the backlog they've had in a couple of weeks, i guess it became too much.
