Dont you see that bitcoin is always recovering from it's dumps? You really need to consider this, ripple is a good coin, but it will never be as bitcoin.
Not sure you are giving a good advice.
At the moment, bitcoin is lower than what it was a few days ago and most of the altcoins are higher than a few days ago.
Even if bitcoin recovers from its dump, Ripple might easily go up another 25% in the next few days, so what do you win?
You want to buy Ripple with Bitcoin? Do it now instead of guessing the future price of BTC and XRP.
It's always wise to do the analysis, read other peoples predictions and then decide. Take it all slow, don't rush it.
Go to tradingview, read what other people are predicting. Every idiot can buy high and sell low and Bitcoin is already down, it won't go much lower. I wouldn't sell it now especially that the lightning network is coming into play.
