you fit store your coin in a Hot wallet which is connected to the internet but this storage method dey risky because hackers fit hack your wallet, storing your coins in a cold storage is much safer because e get enhanced security against all online threat because it is not connected to the internet.
Do not advice anyone that wants to hold their coins to use a hot wallet for it at all, it should be hold on a cold wallet.
Thank you @Charles Tim for the correction, but I was trying to imply that you can store it in a hot wallet when you dey buy am small small before you transfer it to a cold wallet after you have accumulated the amount you want to Hodl to reduce transactions fees. But off course you should store the coins you want to Hodl in a cold wallet for security and better still for security you can still transfer any amount of bitcoin you buy to your cold wallets directly without keeping it in a hot wallet to avoid any mistake or threat of storing it online in a hot wallet
