Bitcoin is one of the cheapest but not the cheapest in terms of transaction in the crypto space. Bitcoin has a lot of privacy and security than any other coin, but if you’re only looking for a cheap means of receiving money, you can try out other cryptocurrencies but their security and privacy is not what can be guaranteed. One thing about bitcoin transaction during transfer it that you should look up to the mempool to see the price of transaction fees before broadcasting payment through that network. It may take short time or longer time depending on the convention on the mempool.
