Haven't you noticed how many pump and dump altcoin clubs are there now?
My advice is to ignore them, pretty much everyone loses money on these pumps except few who r part of it or got lucky.
Buy on fundamentals don't chase these pumps
I agree that pumps on altcoins are common but not as massive as today. They don't usually get over 100-150% and happen once in a couple of days.
I've been in alts for a long time and traded them to oblivion, Above 150% is very common in these pumps. Theyve become so common i tend to shrug them unless im invested in one. Don't even look at the percentages look at the daily volume its nothing compared to how much money is floating in crypto.
If you want to follow big whales for a pump just look at the volume %
