I have the impression that every-time bitcoin starts climbing steadily, the XRP pumps like crazy 100%+ within 24h, causing doubt in the entire market!
Are altcoins like stellar and xrp harming the bitcoin price by their manipulated pumps ?
What do you mean causing Doubt in the entire market?and in only few occasion that Altcoin like Ripple Pumps while Bitcoin is climbing.
Mostly it is Bitcoin will Go first before altcoins like ethereum and ripple will follow.
and also How can you expect a 100% growth in bitcoin while comparing to Ripple the value is peanut.
But about XRP being manipulated?
well that has been a issue for long time now,That ripple is manipulated and there is no Legit Pump that happens.
Though Even how great altcoin move,still Bitcoin will close the market each bull.
