I agree. I remember being excited because one of my regular platform to buy stuff starts accepting BTC but it turns out they only accept wrapped BTC so it's useless if yo don't want to convert your Bitcoin to some random tokens.
Information on available blockchains for deposits, withdrawals is important and your example on Wrapped Bitcoin tokens is good one. This includes big risk of losing money to wrapped tokens under names of Bitcoin, Ethereum, Ethereum Classic and more.
My advice is if you want Bitcoin, buy bitcoin on Bitcoin blockchain. If you want Ethereum, buy Ethereum on Ethereum blockchain and avoid to buy equivalent tokens on other blockchains. Their pegs can suddenly lose and if you hold those pegged tokens, you lose your capital when depeg happens.
