Ripple has been supported by Banks already so reaching the 4$ isn't hard but I think it will take a long time before reaching it. I think Ripple is a good coin to hold because it is on the top of the coinmarketcap. I'll be buying a bit of Ripple in the future and will hold it.
That's pretty hard mate, we're not be able to each $1 and making a way for $4 is quite a long gap for xrp to achieve.
Anyway, XRP isn't in the bull run yet and maybe when bullish will take place over the market will give a huge incline to this coin but not pretty sure if it will be achieving at that price.
