An altcoin being on the "top" doesn't automatically mean it's a "safe" or good investment. I mean, take a look at it! The cryptocurrency market is full of crap. And not to mention that bitcoin is risky and volatile enough for the typical inexperienced investor, and you're going to say that it's better for them to buy coins like Ripplecoin a.k.a. fidget spinner coin? Worst investing advice I've read yet.
I will invest on any of these coins instead of new projects, they have failed me too many times and I don't want to keep doing that, time to move on to old and top altcoins, they are dependable than new coins that only aim on cashing out
