Altcoins today are struggling , yes no doubt about that but if much attentions are giving to some altcoins with lots of potentials, i think it will make altcoins standout in the market. although some altcoins lacks vision and there are several coins i believe will defintely change the market positively.
You need to be careful now not to risk it is not known how bitcoin will behave . If we have already bought coins then wait for their growth.
