Thanks for your answer. Is there any exchange in your mind that has very low withdral fees please? Please keep up great work. Sometimes people are weird and don't appreciate if someone creates something useful. Once the tool has a bit more features I won't mind to pay for it but still need to figure out how to avoid fees. BTW. I noticed that Yobit site has some coins that have same symbols like famous coins for example BCC. BCC is bitcoin cash but on yobit it's bitconnect coin. The tool automatically pairs these coins and shows the difference in price but they are not the same! There are many like this on Yobit. Please be aware exchange.blue.
