some of the coins you mentioned are also good coins, of course it is impossible to take all four coins. XRP and ADA I think are two good coins for now, you can take these two coins, but you should do some research on current prices so that the risk in trading is less.
You are right. Both XRP and ADA are very good coins. But I think ETH and BNB are the best coin for investment. Both are pumping a lot. Both are trusted top altcoins.
ETH is great investment I think. People need it and use along bnb for transfers and I agree - people trust in ETH. I recommend WPP too, check details, you will see potential. BSC network version starts too soon so dont wait.
