I was thinking of something like Tether, but it doesn't appear to have much traction, and the hardware wallets that I have (Trezor and a couple of Ledgers) don't support it so far as I know.
I am holding my funds in Tether right now to buy in dip and you can also do same, many trading platform supports them and consider them as USD.
You can also store your Tether in normal bitcoin address but when you want to use it in future you have to import your private key in omni wallet.
