You can invest in bitcoin, but not all your money. Bitcoins aren't a stable super-liquid currency. They are a volatile investment that will go up and/or down a lot over time. I would not recommend investing more than 30% of your savings in Bitcoin unless you have steel balls and you know exactly what are you doing. Most investors in Bitcoin are tech-savvy people and fintech professionals. If youre not one of them, try something more accessible first (like gold or stocks).
