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 ?
For me i will invest in 5 coins that I will sure that I will be having a profit not sticking on the top coins because they are so expensive, just find a project that has good potential and the development was processing and hold ot for fove years you will see how much profit you will have after that year.
