Usually they recommend you to diversify your investment, so you avoid losses.
But as a real approach, having $1.5k, would you invest in how many cryptocurrencies ?
What if I invest little by little, only in Bitcoin, would that work as well ?
Find promising altcoins to invest into that have small beginnings best one I have found right now is Tera smart money these up and coming fee less instant transaction coins are the future.
Dont split up your already small investment into smaller chunks and put it into 100 billion dollar coins you need to give your self the chance to make 1000x on your investment not 1.5x
