Good choice. Altcoins are far more interesting investment target than Bitcoin and other coins at the top of the market. There are not only more profitable, but their developers used to have a fresh view on market situation. It is definitely wort to support them. I'm investing in alts too, currently mostly in Neo, Dash and FuturoCoin (its developers have recently updated its masternode system, so now you are awarded with some passive incomes when you are a masternode owner)
