Will I save on miner and network fees for sending btc if I import my bitpay wallet to another wallet like electrum or blockchain? I have a bitpay wallet that has received many small transactions. I want to send all of the funds to my trading platform, but the fees are too high after the first send each day which is as low as 1%. Will it help to import that wallet to another client like electrum or blockchain?

It should help. Electrum is better than Bitpay wallet. You can import wallet using seed phrase in Electrum.
Mempool looks clear right now so low fee rate transactions should get confirmed soon.

Ensure that you select BIP 39 option while importing:

Select &quot;legacy&quot; if you had addresses starting with &quot;1&quot; in Bitpay wallet:

I confirmed the first address after importing which is same in both wallets:

In future you can create a new wallet in electrum, move all funds to this wallet. Select &quot;segwit&quot; this time instead of legacy and use RBF for all transactions.
