It's too late to buy Ripple. The pump has ended and a correction is waiting Now it is better to buy Ethereum or Bitcoin, they have fallen very well in price.
If Bitcoin does not go down to 5000$, then I think Ripple is hardly likely to go below 0.4$. So you can buy for long term now.
Basically XRP is a very good coin to invest long term as it satisfies the market demand. So investors can buy into XRP during periods of declining market to hold for a while, I believe it will bring very good profit.
A short term hype coin and that's it. Ripple brings you a short term hype but it will not be a long time for you. Ripple was focusing to create such an ecosystem that brings a lot of bankers to the blockchain and there was no any correlation to the crypto. $0.3 should be the best price to buy ripple and this time this coin looks over valued dude.
