For a while now, certainly in the last 3-4 months I've come across articles online mentioning some concerns with wrapped tokens in general, and I still can't speak to the validity of those claims, I just thought it was something to keep in mind.
You would have done well to tell us the concerns you have been reading about, or maybe post the links where you read them. Take note that wrapped BTC's are not real BTC, if that is what you are talking about, wrapped BTC is an altcoin, so if you must use them, you should at least be aware of that.
