Currently market is going toward the up rise in price for almost every altcoins but still it is not completely recovered, so it will be more better for you to make Investment in all possible altcoins easily .
Currently best coin to buy now is etherium , xvg , litecoin , gem , dadi , reddcoin also because these are going to make a new high price soon ( I get these information from my experienced trader friends ) .
For small term buy hold coin is dgb , because price is not much high and we can easily manage it for the perfect profit for weekly buy and sell .
