Recall that when added to block the miners prioritize transactions with the highest fees. All other translations need to "wait in line", which is called mampalam. The queue is measured in bytes, that is, the total weight of all transactions. The weight of the transaction depends on the number of sent coins.

It is unknown what has caused such a dramatic filling of Nampula. It is suspected that this is the usual “dust attack” with the aim deanonimizatsii some users of the cryptocurrency.

At the end of 2017, the users of Bitcoin have experienced the greatest difficulties in working with the coin. The fee soared on the background of mass hysteria around the increase in the price of BTC to 20 thousand dollars. Fortunately, after a few weeks the situation stabilized.

According to the service bitcoinfees, currently the recommended fee for the average transaction is equal to 4032 Satoshi or 0.32 dollar.
