As other historical rises it finds a perfect time while other alts and btc is not popular so that investor can easily convert to it.
BTC is not so popular? how can you sum up with that statement that bitcoin is not so popular these days? just because you've seen more than 10% growth for XRP so you can say these words? okay its not so popular in your opinion. Some news coming from whatever bank is going to something with xrp means pump is started, it seems like signal from weeks ago are true, they definitely going to sky, i expect 3-4 $ again, i know it is to risky so if you fear stay behind 
I never followed XRP and what are those news that came from "whatever" bank? If you are happy with the current push of XRP then that's good for you and don't forget to sell if you are in profit or else you'll stay greedy and won't be able to sell while its hyped.
