How safe this wallet is?

I don't think it is safe to use and the transaction speed is depends on the network no wallet can guarantee you instant transactions it all depends on the network and the fee unless if it's a lightning wallet but it's not

Another thing that I noticed are:

- It needs email for wallet creation
- No open-source
- It asks for donation every time you made a transaction
- It's buggy after I change the address from Segwit to Legacy
- Turning back to segwit does not work.
- It has some ads(Tracker)
- The wallet looks the same as Coinb.in wallet
- Yes it does not have ID verification because it's not an exchange. A wallet like Electrum does not ask for KYC.
- It doesn't work offline
- The buy and sell button redirects you to bestchange.



So how can we sure if our funds are safe?
