To store bitcoin, I purchased the hardware purse Leger Nano S! He has some features, but I'm generally very pleased with the work of the wallet!
I don't know how much BTC (or other supported coins) he has.
For less than 0.1 BTC a hardware-wallet may be too expensive in regards of the possible profit.
Cold-storage on a malware-free computer should usually be enough in this case.
Otherwise go get a hardware-wallet and ofc never use online-wallets for higher amounts.
Well,if it's a small amount,it can be expensive to buy a hardware purse,but it's a very convenient thing!And about cold storage on your computer without malicious programs-it's not so easy!I bought an antivirus, but he did not protect me!
