bitcoin payment high fees I am using bitcoin-rpc and everytime i create an invoice for the client to pay, i create a new address. Payment is ok, i get the money after a cron.php sees that all confirmations are above 3, but then when i try to send my money back to my big wallet i see 200 300 usd in fees
bitcoin-cli sendtoaddress &quot;MY_WALLET&quot; 0.1 &quot;&quot; &quot;&quot; true
I see on blockchain that everything was sent from each and every address that i have created
ADDRESS1 ... 0.05
ADDRESS2 ... 0.08
ADDRESS2 ... 0.028
... and so on
How can i send everything from one big address and pay only 20$ usd fee?
I think i pay per vbyte for what i have read ... but i want to send internally with low or no fees or something. Can i send coins internally to one big wallet?
I mean don't think that big payment gateways that do the same thing and create an address for every invoice but pay such amounts of fees.
Thank you.

No.
By internal you mean without communicating with the Bitcoin network and without involving external miners.
All Bitcoin transactions which move money from one set of Bitcoin addresses to another Bitcoin address are external in the sense that they must be recorded on the blockchain and therefore must incur transaction fees.
