Please help me not get scammed

HELP NEW TO THIS

So to preface I’m 17, I have been following Crypto currencies for almost 8 months now and have €7.5k that im willing to invest (I understand risks and all that) I’ve recently been drawn in buy Ethereum as currently right this minute i can afford 2.5 ethereum. although as said im 17, my mother is letting me use her information to buy crypto although i dont want her knowing how much of my money im putting into it. its money i made and i don’t want her input as she knows nothing about crypto and will be critical. im using coin space (app called coin bitcoin wallet) and they use moon pay to exchange.they’re asking me to make a bank transfer to their iban to complete transaction. i just want to verify this is a legitimate transaction and common part of the process. thanks in advance.
