Every time any amount of digital currency is exchanged, the currency goes through a blockchain. This process requires a small fee called a ‘network fee’, which is actually a commission taken from the amount sent in any currency. It is important to make sure that you have enough funds to cover the exchange fees both for sending your original currency and receiving the new currency you want to purchase. The transaction will not go through and the funds will be lost in case the amount is too low to cover the fee, that is why it’s vital to ensure you have enough funds before making a transaction. The fee equals to 0.5% commission for each transaction. It is taken before your funds are sent to the recipient right after the exchange process is completed.
The good thing about Changelly is that it has no minimum or maximum amount limits, apart from the cases when the set amount is lower than the commission necessary to cover the network fee. This attracts small traders who are just interested in testing the waters, and large traders who are into exchanging big amounts.
