This tutorial will show you how to withdraw Solo from the Bitrue exchange into your XRPLedger based XUMM-wallet. PS: You can use multiple different wallet apps for the same xrpledger address. The wallets are actually just interfaces helping you to communicate with the xrpledger. Your tokens are at the xrpledger, not at xumm.
Xumm and the Solo dex are both interfaces communicating with the xrpledger. When you use any of them to create a wallet, you actually create your wallet directly on the xrpledger, which mean that you can use One xrpledger on multiple interfaces.
This tutorial teaches you how to use the most popular xrpledger based wallet called XUMM.
This tutorial shows you how to trade xrpledger based tokens / assets / currencies on www.sologenic.org and how to do it with the Solo Dex APP. You get a three step clip showing how to execute a market buy order of the solo token.
