Yes, we will never know what can happen in this crypto anything is possible, maybe what we have can make us rich so it is important to split our money into 2 or 3 differents coin. I am not a big fan of btc, But to be honest it is little hard to replace or beat btc because btc is the first coin in this crypto, the popularity and the price is so fantastic, it takes years for other coin to replace or beat btc.
