Always follow the first rule of the Investment in the altcoins ",never put your all the eggs in the single bucket ".
So here I will suggest you to put your money in different different altcoins instead of single altcoin .
Because sometimes it may happened that the particular altcoin goes died for long time or Became at stable price for long ago , so if you will put youroney in different different altcoins then Thier will be less chance of the risk to loss and you will make better profit ( and this will.down the chances of the loss ) .
I will suggest you to out your money in the DGB , BTM , creva , Putin , eth , dash , rdd , edr , ripple , monero etc .
