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 ?
Depending on the stage. I will not diversify too much of my investment resources. Because when I divide the investment, I will not get too much profit. In my opinion, for $1500 I would divide it into 3 and mainly invest in bitcoin
