Best case (compressed address, lowest "recommended" fee rate):
148 bytes * 250 sats = 37,000 sats per input.
NOTE: If it is an uncompressed address used it could be 180 * 250... = 45,000 sats...
So, if you have UTXOs that are less than 0.00037000 BTC in your wallet... and your wallet calculates dynamic fees... it will probably tell you that you have insufficient funds to send them... as the fee required to send that input is equal to or larger than the input itself

Pretty much the only option is to manually select all the dusty UTXOs from your change addresses... manually set a fixed fee that is calculated to meet the 10 sats/byte (0.00010000 btc/KB) rule for ViaBTC... and consolidate all this dust into one output back into an address that you own. Then attempt to accelerate the transaction using ViaBTC and cross your fingers :-/
Thank you for the extremely detailed explanation.
Would you be kind enough to explain how I'd have to proceed to consolidate all the dust into one output back ?
I'll send you via PM two SS's of my Electrum wallet along with the change addresses, I also have the same problem on Blockchain.
Thank you!
