......but i can not increase fee to the main amount only to the fee i boosted with the first time should i increase that fee even thow the main transaction is not confirmed?
Now you have two transactions.
The first one was made by someone else to your address. The second one was made by yourself for doing CPFP and that's the one you can increase its fee.
With increasing the fee rate of the second transaction, you will increase the effective fee rate of the first transaction and they will be both confirmed at the same time.
yesterday i bumped the fee too 150 sata and today i bumped it to 200 sata and also accelerated it on several places blockchain.com says the transaction is invalid. and viabtc says transaction unconfirmed. should i bump it to 250 or 300 sata?
