How do I send stablecoin to a source?

[Quim]

Would it be possible to explain how a transaction using USDC works? If I understood correctly it could go like this (at least for my case):

1.) Have in my Tangem wallet some SOL for gas fees.
2.) Using Kraken Pro; buy USDC.
3.) Transfer from Kraken Pro to Tangem using ERC20/Solana networks.
4.) Transfer from Tangem to QSC USDC using again (?) SOL gas fees and using the network ERC20/Solana?

Isn’t it possible to buy USDC on Kraken PRO and send it directly to the seller’s wallet?

EDIT: After reading the rest of the thread, I realized you prefer to send it to your own wallet first for privacy reasons.
