Wallets for BTC and ALTs

[MikePC12]

Hello,

First I must say that Im new to here. My question is written below.

Quick question regarding crypto storage: Is there a way to store bitcoin on a laptop/ usb drive / mobile without needing a lot of HDD / SD card space ?

I need a wallet / solution file that would not take up space, yet be accessible at (a fairly) short notice.

--thanks all--
