The easiest way to buy Ripple is through Gatehub.net, which allows to deposit FIAT via SEPA or ACH, as well as other crypto. Once you go through a Simple KYC process, they will activate your Ripple wallet with 20 XRP for free, then you can use their platform to trade against a bunch of Alts, BTC, and FIATs at the same time, regardless of the surge they're having now from the increasing number of customers, I'd only recommend them for Ripple based transactions, let alone that ripple.com chose them for their incentive a couple of years ago or so.
