Your money is definitely safer in the bank, although in crypto you have the private key and have full control of your money but the problem is the user is not that careful to guard their own money. It's a choice between putting your money in the bank and have more security or putting your money in crypto and let the value of your money grow, there's risk of inflation in the bank and there's investment risk in crypto so it's really up to the person himself.
Yes. It all depends on the specific person's needs whenever he/she wants his/her money to grow at a fast pace with a high risk involved, or simply secure his/her money in a bank account. Honestly, I would choose both since banks provide you with security you know and trust, while cryptocurrencies provide an endless profit stream and complete freedom. If we were to compare both in terms of security, then cryptocurrencies beat banks by a long shot. This is simply because they're decentralized and are not controlled by a specific person, or company.
With banks, you risk your funds of becoming manipulated by governments, and losing all your hard-earned money. After all, banks are custodians of your money and they have complete control over it, allowing them to do with it as they wish. On the other hand, cryptocurrencies give you the power to control your own money your own way, as long as you have access to the private key yourself. By taking the necessary precautions to secure your cryptocurrencies funds by staying away from online wallets as much as possible, not leaving your coins in an exchange, and more, you can rest assured that your money will be safe in a cryptocurrency if its blockchain remains alive.
In the case of Bitcoin, it's the most secure and reliable cryptocurrency which is hard to take down by any single entity. As such, you can feel confident that your money will be safe in Bitcoin if you follow the practices mentioned earlier. However, the biggest downside is the volatility inherent within the pioneer cryptocurrency, which could be much of an issue if you're thinking in short-term saving rather than long-term investing.
Therefore, it's up to you to choose whenever you'd like to secure your money in a bank, or in a cryptocurrency like Bitcoin. Just my thoughts
