If you put $100 into BNB today, you'd have around 0.133 ETH.
If BNB ever reaches $5,000, that investment could turn into about $666.
Now, take the same $100 and put it into XRP — you'd get 28 tokens.
If XRP were to hit $1,000, that same investment would be worth $28,000.
Same money, totally different potential.
