No other name will be as good.
There is a possibility that bitcoin can get replaced by any other currency in future only if the new currency would be holding better benefits then bitcoin and if that happens then people will surely switch to that currency leaving bitcoins behind.
This is harsh but undeniably true! There is a possibility. This is unavoidable if bitcoin will not evolve and improve itself. For example, the elapsed time in order to confirm transactions. If the confirmation will take long, then others may use alternatives such as using fiat (especially if the transaction is a face to face payment). The confirmation time of transactions is impractical today because people prefer instant. If a new currency will adopt the characteristics of bitcoin and then implements the improvements (such as the one mentioned earlier), the tendency is for people to shift from bitcoin to the new one.
Yes delay in confirmation time is an major issue at a moment and even the fees have gone higher so if new currency will have less fees and instant confirmation then it will take no time for people to leave bitcoins behind and adopt the new currency.
