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.
Yes, now alts look very good and promising, but also alts do not grow in price so far, now you need to choose and invest if there are no coins in your wallet.
its mean you should choice good altcoin has potential for future because there is altcoin not grow very well and if you investing on this coin you will get lose with your balance. you alright its good time to buy but before buy you must to choice potential coins maybe like Ethereum, Litecoin, BSV and BCH
