I think this 2020 is the best time to buy Altcoins. There is a huge promise that Altcoins will really touch the sky when the rise up does not end. It is the best time because some are still cheap to buy and these coins are starting to go up on the market chart.
As long as bitcoin is still going on to the moon and we have a huge chance to see that. It's not about this year is the best time to buy altcoin or not but just try to remind you if the best time to buy crypto should be on the bearish market. We just need to follow what already done by the whale.
