I guess the system is really worst and the transactions are hidden, but I maybe it's just too early to assume this thing as they are just getting started into crypto for sure there will be changes.
- You dont own the keys
This is probably their disadvantage since this is more like a custodial bitcoin wallet.
To recap :
- You cannot withdraw your Bitcoin
- You cannot Pay anyone ( ironic ) , so it can't even go to another PayPal account
These two are something that I highly doubt for sure you able to withdraw your bitcoin and at the same time you could pay anyone with bitcoin at that account otherwise no people or investor is gonna use this system at all.
Without these features, it's just useless and it will be a huge failure, so for sure, there will be changes and updates about it.
