I have a 12 recovery seeds that won't import into Electrum, it will give me where to type the words and I carefully checked them to confirm if the words are correct ones but Electrum won't let me import because the botton to do so isn't available, it's blank.
Anyways, so between Blue wallet and Cake wallet which one is good enough for small amount of Bitcoin? Nothing too big for long time, just for small transactions here and there.
I read they are both open source, is that true? Which is best and why?
That's a good question, as we all know both wallet are open source and generally well regarded, so either of them is a good choice for storing your holdings. Both wallets has theirmain functions, so if you're into pure bitcoin holdings/investment, then I recommend you to chose the blue wallet because its a user friendly especially to a beginners here. It includes some useful bitcoin features such as native SegWit support, watch- only wallets and hardware wallet. As for Cake wallet, it's a good option too especially if you want to manage your bitcoins together with different type of cyrptocurrency holdings... But like what i've mentioned, if you want to focus in bitcoin only then you must consider the bluewallet as they offer a more streamlined experience.
