Want to quickly and easily exchange Steem Dollar for Polymath at a favorable rate? You are in the right place! Changelly offers low fees, secure exchanges, 24/7 support, and a functional user-friendly interface. Here, you can exchange cryptocurrency at a fixed or floating rate. In the first case, you can “fix” the rate for 15 minutes. In this way, you will be protected against the volatility of the cryptocurrency market. However, remember that in such a case, the processing fee is higher. If the rate increases, this possibility can help you save a significant amount of cryptocurrency. Alternatively, clients can pick a floating rate and take the risk of the exchange rate change. Exchange SBD for POLY on our platform or within the Changelly application.
