Since this post was created, it's nice tonsee how most of the key players mentioned early last year are still active and live altcoins a year later.  It is with the reasons mentioned by most users that got me agreeing on why these coins: litecoin, ethereum, ripple, and dogecoin.  Transaction values for these altcoins continue to remain progressive despite thevolatility that the crypto market is known for.  Also not surprising is how we still have strong followers for these mentioned altcoins because of the excellent project team behind which sustains the momentum and growth of these coins.  So once more, I say this with belief that these altcoins will continue to survive this 2018 and the years to come.
