when you talk about dust would you consider 0.01 BTC dust? i don't think so but I ask.
It's not dust in the sense that it still has/had value at high fees. Last December, fees went up to 600-800 sat/byte (and shortly even higher). If/when fees go up that high again, each input would cost you 0.001
BTC or more in fees, which is 10% or more.
Let's say you have 10 small inputs of 0.01
BTC. If you consolidate them now, you can pay 1 sat/byte and get around 0.09998
BTC as output. If fees go up to the peak again, you would get less than 0.09
BTC. That's why it's so important to consolidate your funds while fees are low, it makes it cheaper to use your funds later on.
In case i wanted to consolidate you advise me for example to send 1 entire bitcoin from my ledger to an other address of my ledger and keep everything saved until now in a new unused address belonging to my ledger nano s? I never did that just asking if it is worth it to anybody that knows here
