Why not 100$ or 1000$?
5-10$ in 10 days is absurd, XRP already has a large marketcap and your prediction would mean that in case of 5 $ the marketcap would the same as BTC around 200 billion, in the case of 10$ marketcap would be 2x times of btc marketcap. Think twice.
Because $100 or $1000 is too high for the XRP at this year or in the next year although it could be possible to happen. I think XRP can be back to the last high price before if the bull market arrives in this year. But that need works from the team to keep support XRP so the coin can go to the high price. So let's wait for what will happen later, and we will know how much price for the XRP.
