Most of them are not uptodate and taking that transaction cost as it is at that moment is not easy neither. I imagined a website like this before, but not a website that just creates a call and gets the costs alone, I also considered adding "what is the cheapest way to move x coin from one place to another" type of deal. Even could be increased to "how to turn x coin from y place to h coin to b place" type of deal and finding the cheapest methods.

I wondered this because there are too many people in the crypto world with nearly dust levels of coins in multiple places and if we could just get them all to one place at the cheapest possible solutions then we would have a good amount saved from there.
