But talking about safety: if exchanges like coinbase would end up failing, i am pretty sure that those fees don't matter any more. Because places as legit as coinbase failing, would mean that something horrible has happened and value of that btc would be tanked overnight so much, and that point selling it would be just covering your losses.
Do you know of reliable sites that can display network fees for different tokens, and if not, how one can find that out?
Coinbase, which I'm not a big fan of, goes down, it'll be because of something like what FTX was doing. And if so, whatever deity you pray you, help us all.
