Look what you wrote,pay attention: " I am looking for a best exchanger where transaction fee is too low and listed a lot of coin in any other exchange. "

if you were to evaluate an exchange according to this: a best exchanger; where transaction fee is too low; listed a lot of coin in any other exchange..

you will run the risk of getting into some exchange scam. you should evaluate the following:

1-) The owner of exchange
2-) if the exchange has some physical office in real life
3-) if the exchange has any telephone number
4-) if the exchange has no scam accusation
5-) if the exchange provides good services (support ticket support with the shortest possible time)
6-) if the exchange is regulated by the government

see that I do not include the low fee and i do not include if the exchange list many coins. Why? because safety is in the first place.
