Until we can make large purchases such as any cars or houses with crypto, we'll need to convert to fiat for the time being.
I know that in some regions, making those purchases in BTC is feasible but that's not the case in most places yet.
There are quite a few services and some major corporations around the world have accepted bitcoin in the deal. Some corporations also research and develop their own coin. Now that the market is recovering after a few days of declines, it is now a good time to buy more potential coin to prepare for the bull run in the next few days.
