Oh surprise the Dash is down itself now! Here it what happened: Crytpo market is same throughout from Bitcoin to Z of Cash! :-) No matter what where you invest your investment will go up some day for sure. With the current dump we have opened up lots of opportunity to invest into crypto currencies because almost whole market is down at the current stats. So with that math in consideration we can actually divide your $500 into top five coins easily. Lets forget about the bitcoin for moment and you can still have at least 9 different coins to invest in. Im thinking you should really go with the NEM, IOTA and ETH. Waves is also good but one must look for the safer zone which is with the three coins that I have mentioned above.
