I think it's better bitcoin, but not today. you have to wait for bitcoin back down. because I predict it will still go down.
and I see also some good altcoin to invest like NEO, FLXX, Riple, ZCash, UTT, Ignis and others. and I prefer the Ripple because Ripple's stock reaches trillions. and will last very long.
you are contradicting yourself here!
you can not both predict a bitcoin price fall and at the same time predict an altcoin price rise. it will never happen like that unless an exception occurs which is rare and it will not be in the big coins. the exceptions will be small coins that nobody even knows of which are getting pumped regardless of the general market direction.
if bitcoin falls altcoins will follow like they always do.
