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 ?
as a beginner more people invest gradually, because there are many benefits that we can get by trading in stages because we will indirectly learn about bitcoin and price movements from time to time, because we in the future can make choices by knowing the potential price increases which we have mastered gradually, other benefits if we are wrong and experience our losses can be avoided from losses in large quantities because we do not put our money at once.
