Is it possible to accelerate the transaction not by bitcoin, but by another coin using the ShA-256 algorithm?

I sent coins from one stock exchange to another - for two days now 0/20 confirmations
Can someone encounter this situation?

Of course on a fee basis

Please help me with transactions, stuck from 6 Dec:

Thanks

Unfortunately the free acceleration didnt help. What options do you offer for accelerated paid service? What are the success chances? We can also discuss in PM
