what the title says 
As long as it wasn't an online wallet it should be fine.
Im using Electrum as it can be considered as one of the best choice wallet if ever those so called chain split will happen. But still today, Im using an online wallet (or should I say exchange) just to use their service as they're the only one who can have cashout feature or using bitcoin for other services.
One of the best wallet i've use and maybe that could be the main wallet after the split happens, But for me I will exchange my btc to waves and ETH temporarily since this coin are pretty much stable for now since I think these coin will pump up when days before august will be near to come.
