as price is going down what is the best stredigy for for altcoin
Buy alts that have good potential in the future. While the price is dip, this is the best time to buy for good potential coins in order to have good profits in the future.
I think there is no need to buy altcoins anymore, if you look at market conditions that are not good. Just holding an existing coin does not to adding a new coins just burden by holding another altcoin.
