If you want multiple currencies you should probably look into a payment processor such as coinpayments or btcpayserver.
If you just want BTC, use bitcoin core. Assign an address to a user and enable walletnotify. On deposit you will get notified and you can process the deposit however you like. Should be scalable.
Yes, bitcoin core fits well with what I have described, but I would like the user to have the opportunity to use other currencies(4-5 popular currency ada, eth, usdc), unfortunately, the specifics of the my site do not allow using the payments services(coinpayments or btcpayserver) that you mentioned. at the moment I'm leaning towards binance with its ability to create sub-accounts in a business account via api.
