I am altcoin collector and i never sell what i get and just wait. I would suggest you some altcoins price under 1 dollar. I believe that those all have bright future.
Einsteinium (EMC2) 0.86 USD
Ripple (XRP) 0.252470 USD
Stellar Lumens (XLM) 0.091140 USD
Bytecoin (BCN) 0.001999 USD
Golem (GNT) 0.32 USD
Dogecoin (DOGE) 0.002233 USD
I'd took DOGE and BCN out... and put NEM (XEM) in.
They seems to be very professional, even though they are not listed on many exchanges (most of exchanges are really costly to be listed, and the NEM Foundation is focusing right now on development than marketing).
Also, they are planning to launch the Catapult really soon...
the right time to invest because the price is still under $ 1, and may be able to earn a profit in the future if the price can be above $ 1 and get a big profit.
