I mostly get my bounty rewards in BSC coins but this time I got in BTC and the fees are pretty high.
I did some research and found out that I can move my btc private key to another wallet, But I don't know if it's safe or not, I can use this and wait for my other btc payments and then move.
How many BTC payments have you received so far?
Because each of those inbound transactions are saved as separate "
unspent txn output" in the blockchain.
And when you need to send all of your funds, the transaction will have to use all of those inputs; each added input increases the total size (
in virtual Bytes) of your transaction.
The higher the vSize, the higher the absolute transaction would be, for example:
If your transaction's size is 10000 vBytes for having a lot of inputs and your fee rate is 5sat/vByte, the total fee will be: 50,000sats or 0.0005 BTC.
On the contrary, if your transaction has a low size of 200 vBytes, the total fee for 5sat/vByte will only be: 1000 sats or 0.00001 BTC.
