my advice is 40% in ETH, 40% in BNB and 20% in XRP, because I prefer to invest in ETH and BNB, therefore the percentage of ETH and BNB is bigger than XRP, but I still recommend you to DYOR, because you invest with your own money, so you have to manage your finances and the amount that you want to invest by yourself, because a good investment is an investment that we choose for ourselves (DYOR).
