Hello HN community, I'm just curious about the rise of this new BitCoin currency. I'm currently developing an Saas product myself, so I'm actually torn between choosing various currency processors/vendors.<p>Can someone explain as to<p>1) Why and when one should use BitCoin?<p>2) What advantages does BitCoin have over traditional payment processors like PayPal/Stripe?<p>3) Is there any legal downside of using BitCoin? (For example, I read somewhere that Bitcoins are used for Money Laundering and the governments are actively monitoring anyone using BitCoins)<p>4) How much do you save (if at all) by going with BitCoin instead of someone popular like PayPal/Stripe?<p>Thanks!
