Not sure what's the reason behind this pump but most of the time XLM moves like this when XRP is also pumping, it's a good timing for those who bought a week ago as the profits is almost 40% now and we all know when some pump happened with the coin, those who manage to see a good amount of earnings will think of selling and collecting their profits.
Let see if the week will end with continuous positive run for this coin. Just be very careful with your decision in case you are still playing/investing with this asset.
My friend bought ХLM for a long time, he told me that it would be a good investment in the future, but I didn’t listen to him because I don’t have a big budget for buying different coins and I only buy BTС so far. And my friend decided not to sell his coins on this pump, he says that ХLM will grow even more and he does not pay attention to temporary pumps.
