In May since the decline in bitcoin, altcoins have also fallen until now, and many traders in the world are stuck at a fairly deep peak and many have cut losses, is this the work of bookies, what do you think?
Whenever bitcoin is pumping, Almost majority of alts specially the low cap tokens/coins will bleed or dump since majority of traders are converting their alts to BTC. This is a normal trend on every bitcoin pump, so in case your holding alts that is bleeding, keep hodling them or just sell to lessen or minimize your losses.
