Now is the best time to invest in altcoins because bitcoin is surging very high without altcoins joining the game changing pump yet, I'm guessing by January 2021 it will be too late to invest in altcoins too so now is still a good chance to get some altcoins
but I'm not sure now is the right time to buy altcoins, because the increase in bitcoin will affect the decline in altcoin prices, so my prediction is that until January bitcoin will continue to increase, so it's better to wait longer to buy some altcoins
