I chose both, bitcoin and ripple can be a good investment for profit, but for the most part of the money I invest in bitcoin because it is the most powerful coin.
I'd invest in Bitcoin. Investing in Ripple does not give me any benefits from holding it for years, if I hold it for 1 year the coin could be worth a small fraction of the purchasing price because of the reputation it has.
Of course Bitcoin has many flaws. This cryptocurrency is not perfect but at the same time I understand that there are many complains about Ripple from experts. They think that this currency is control of its developers. So I prefer Bitcoin.
