This may be a dumb question but why not do it in one big transaction to save on fees?
Whether if it's a $10 transaction or $10,000, if there's only one input and output, both will have the same fee and will be cheap even with 100+sat/b fee.
Transaction's fee is not based from the amount being sent, it's based from the
total size and the fee rate.
The
size will be bigger if there's more inputs and slightly bigger with more outputs, the type of address can minimize the size too.
I'll edit this later if found anything.
-Edit-This may be inaccurate, based from questionable sources.
If you follow the trail of those 14.something BTC transactions, you'll see this transaction:
576ff94ee61525ed30fd5537b69ce65d9bde3ffce8441c1040a547f8bcedc046 that sent a bunch of exactly 15BTC to multiple bech32 addresses, each might have been used for sending solo/priority withdrawals (
they saved some fees since it's one input-two outputs tx), then later consolidated.
Next, if you follow the "
hot wallet" you'll stumble upon the wallet dedicated for huge balance:
