Here's the website to those who are curious as to what OP is talking about.
https://www.oobit.com/Kinda similar to Crypto.com. Offers debit cards, buying crypto with fiat, etc.
It is centralized and managed by a company and with that comes vulnerabilities, susceptible to hacks and data breaches. Doesn't sound so secure to me.
Yeah and being a centralized then this is really not the type of place where we wanted to deal with our cryptocurrencies.
Hacks are indeed to be find more often in such so yeah i will not use this as a platform where to buy crypto and OP's claim isn't secure at all.
