I think it's more safer if you will convert your bitcoins and put them in your bank account. The value of bitcoin is very unpredictable and risky if you will put everything into investment there is a big chance that you lose everything while if yoh put them in bank though has littke income but you can assure you will not lose them
Yeah. You can never depend only on Bitcoin, as it is an extremely volatile cryptocurrency. Every once in a while, you should sell a certain amount of your Bitcoin to fiat, to help save the value of your investments and avoid losses when prices start to decline.
Therefore, if you diversify your investments, you'll be able to minimize the risks and preserve your financial future. Combine this with saving money, and you'll be all set.
It's only a matter of choice whenever you want to stay with Bitcoin, or diversify and look for other options, along with saving that will pave your way towards wealth. Just my thoughts
