I believe that if you plan to accumulate bitcoin, you should also take care of its security. Today, you may only invest a small amount, but over time that amount will grow and no longer seem insignificant. You don't have to buy a hardware wallet right away. However, once your bitcoin holdings reach a value that you would truly regret losing, purchasing a hardware wallet becomes a necessity.
It's hard to say which value is large enough to start consider about security more seriously. You can not buy a hardware wallet but at your start with Bitcoin, security must be a thing you need to learn. It's your keys, it's your coins, and only good security can help you self-securing your bitcoins.
Cold storage is used to ensure maximum security of assets from online hacking. Those who are aware of their crypto will be interested in accepting this service. But the service is especially suitable for those who want to hold their assets for the long term and who are willing to keep a large amount of assets safe.
"Large amount of assets", in my opinion, is not only related to the value, it can be a small fund with others but with you it's large. Especially if you consider your money is valuable with you, it's always large one. Accumulate each small (but large if you see it important) fund, with time, maintain it a long time, you will have a larger fund.
So with any fund value, let's secure it and take it like your chance of practice with wallet, security, and privacy.
