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 ?
I also think this is possible. We witnessed Bitcoin stalling and not testing 20k and altcoins like XRP and Stellar suddenly making 100% in two days. Altcoins rising extremely fast is a bad indication of a bubble forming. This rise was not understandable as nobody cared to invest in XRP or XLM and there wasn't any news of these coins to be used for something they weren't already.
Perhaps Grayscale bought some to sell to the institutions as "diversification".
