Be aware that WoS could be gone with your Bitcoin tomorrow.

Only keep amounts in there you might need in the next days and maybe choose Blixt, Phoenix, Breez …whenever you can.

I personally see no problem in custodial services and I am thankful for WalletOfSatoshi. As long as you are aware and know your risk using their app is ok imo.

People never wanted self custody. They don’t want it yet and not in 100 years. 90 % of people are not able to take responsibility for themselves and that will never change.
