There are lots of coin and tokens out there but Bitcoin is always the best because of it originality. If you are buying coin from your preferred exchange that's nice because you signed up with them but it would be on a safer side for you to transfer your coin immediately after purchase so as to avoid hearing stories that touches the heart because these days it is just funny how we sleep and wake to hear about sad incidence of hack and crack. OP I believe you must know how to set up a wallet so it would better you do that on your own so as to keep safe your passphrase because that's he key to your wallet rather allowing someone to install and activate your wallet for which gives them access to your assets. You gat to be smart.
