Is there any upcoming project that would act like a bitcoin savings account?
What do you mean bitcoin savings account? is it like a bank that giving any interest of the money you lend it to them.
For me it is good to do bitcoin savings through putting it in the bitcoin wallet address. Like Electrum, bitcoin core, multihd, and etc.
No need to expect the bank to come. Because you do not have to expect interest saving when the bank is present. You can keep your bitcoin in your wallet and then you can also make a profit from price changes. Because it is certain that bitcoin prices will surely rise. You just need to save and wait
