Where to buy ripple?

If you're from Europe, you can purchase Ripple directy from Litebit.
If not, I suggest buying BTC or ETH (preferable) and have that sent to an exchange like Binance.

As you've never used cryptocurrency before, I'll make a quick list for you of what to do.

1. Create an account on Binance (don't forget to enable 2FA).
2. Find a website where you can purchase Bitcoin or Ethereum.
3. Go to Binance and copy your BTC/ETH address. (can be found on the funds page)
4. Use that address from Binance to send your purchased cryptocurrency to.

After you've done that, exchange your BTC/ETH on Binance for Ripple.
Just try to fiddle around with Binance and you'll likely figure it out easily.
