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!
Well it's a good thing that you know some of the coin that are very relevant in this time and you also have funds to make purchase of them, though it is good you make you research about them before investing in them because the crypto space can be so deceiving a times, you think that you have carried out the best decision just to discover that it was the worst, so don't just throw $3000 into the pit, make sure you make your own research.
