Well, I must notice that the choice is only up to you. But if you're newbie and you’ve just entered the crypto market, then, probably, it makes sense for you start with Ripple. Of course, Bitcoin is good investment as well, and it's widely used by people, but it's very risky. This coin is highly volatile and you should gain some knowledge and experience before you start dealing with BTC. So, as for beginning, try to buy XRP. Only after you feel you can go to the next level, switch to Bitcoin. But keep in mind the fact, that you’ll be needed to make a deep research and be very careful.
