There's a balance between showing your friends you appreciate them, and flaunting wealth / buying friendship. The general rule I think is: don't gift something a friend can't repay with equal social value in their own way. Or if you're going to anyway, make it explicit you're doing it for the experience, and don't make it a regular thing. (E.g. dinner at a very expensive restaurant you want to experience and you don't want to eat alone.) People know that rich people do rich people things, and "fun experience" is something that can be repaid without spending lots of money.
