With current BTC pull, almost all altcoins went up to some extent. However, XRP is the one of the few coins that went up nicely. Last time, I checked it almost a week ago, it was around $0.275. Obviously, those of us who had invested in Ripple could have made some nice profit. Though Ripple beat Ethereum after 80% price surge. However, at this time Ethereum is back at no.2 once again. There are several reasons behind XRP price surge and not all of them are true.
Ripple has been regarded as banks' coin and for that reason the advocates of decentralization has been very speculative about this currency. Banks uses their influence and funds to create FUD and thus panic selling and buying happens. You can read here more details on reasons behind Ripple's price surge.
Will XRP go to $5? Well, I'm not sure whether it goes to that mark or not but one thing that I'm confident about is that there would be lot of manipulation about the price of this coin in particular. You can make a lot of profit OR you can lose all your money. So, invest what you can afford to lose and always apply stop loss.
