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!
I dont think so. We can use fiat money to invest in stocks or real estate, etc .. These are tangible assets and it is always profitable for the holder.
