As of right now, you cannot buy MRPH on Binance. However, there is a way to buy MRPH indirectly on Binance by first buying BTC or ETH on Binance and then using those funds to buy MRPH on another exchange.
The best way to do this is to first buy BTC or ETH on Binance using a credit or debit card. Then, once you have your BTC or ETH, you can transfer it to another exchange that supports MRPH trading.
At the time of writing, the only exchange that supports MRPH trading is Uniswap.
To do this, simply create a wallet on Uniswap and connect it to your Binance account. Then, you can use your BTC or ETH to buy MRPH directly on Uniswap.
Once you have your MRPH, you can either hold onto it or trade it for other cryptocurrencies on Binance.
