A lot of people have always worried about the security of bitcoin and cryptocurrency which is why they have decided to stay away from investing in it. You must also note that even the fiat money that you may have can also be liable to theft. The earlier you stop giving flimsy excuses, the better. The decision is yours!
Moreover, I want to say that keeping the crypto currency is safer then other currency. Sufficiently hide the key from your wallet and that's it. But with fiat money everything is different, they occupy a certain space for storage. And if you take them to the bank, then in many countries they will ask questions about where you take the money. It has long been an understandable fact that electronic money is more convenient than cash, and crypto currencies are perfection.
