I don't get how to buy ripples from Bitstamp. I added some BTC from bitstamp to my Ripple account but have not figured out how to convert them to XRP's
Advanced -> Trade
btc/xrp
for btc select issuer bitstamp.
down there's "my orders" | "order book"
press order book
Now you should see the current order book for bitstampBTC/XRP
Is it true that you need 300XRP's to get started trading with BitStamp? If so I can sell 300 XRP's to any one who need them to get started.
200 is the minimum to create an account (and those 200 can't leave that account).
+50 for each offer/trust line
Since you need to trust bitstamp** and make at least an offer, yes, you need 300. But if you want to have more offers, you need more reserves:
https://ripple.com/wiki/Reserves**You don't need to trust bitstamp to buy bitstampBTC, since an offer buying them implies that you trust them.
But you need to trust them if you're depositing the IOUs directly from bitstamp.
