I will recemend you to buy only coins with good name in market and avoid shit coins, TRX, XRP, NEO, ETH, LTC, XMR are some projects with Trusted team and comunity in backup. Hope you will consider my advice.
your mentioned is quite good to buy.But I think buying XRP is not a good decision.Because maximum time XRP failed to break the btc pairs.better you can replace XRP to the BNB.last 2 years BNB ROI is good enough.And BNB borked the btc pairs so many time.In my view you will get better profit than XRP.BTW before investing your money you should make your own analysis.
