Hello,
I'd like to invest in some cryptocurrencies.
It seems BCH ETH XRP XMR are the top coins.
I have about 3000 eur, in what percentages should I differentiate my investment?

Thanks for your suggestions!
I can say that. The easiest question to ask on YouTube. Look for someone who shoots video. With a large number of Sub. I think there they will tell you which coins are more relevant for investing. And they will bring a living example of why.
