i would say Bitcoin cash and ethereum classic. both are in top 20 but for no a good reason. just cuz of their name maybe

i dont know even why there is an alt as etc and what it is for ?
really why people use etc or buy or HODL ?
tether also its not in top 20 but currently 21th on list. they just give market tether every time and with no reason. i think that would be problem after a few months.
I have to agree with the ETC, there doesn't seem to be much enthusiasm for this coin. Not sure about Bitcoin cash, that could be a dark horse but I'm not willing to put money in it to find out.
