Binance allows traders to convert their dust into BNB. Using taproot, https://www.binance.com/en-MX/square/post/18878041020370 this allows the cooperating participants to operate protocols such as LN or vaults using UTXOs that are indistinguishable from single-key UTXOs, improving both participant privacy and onchain scalability. ● Joinmarket has two types of users: those who pay to coinjoin (market takers) and those who are paid for allowing their UTXOs to be used (market makers). But he or she should be competent enough to know the working of forex trading or stock market. Trades cost 0.1% on both spot trading and margin trading, with discounts available when users pay with BNB. However, scrypt-based currency mining, like Litecoin mining, is still cost effective. It is unfortunately not particularly cost effective to mine bitcoins with a graphics card on a home pc anymore.
