Is that UnitedBitcoin an altcoin? if that so, it is very impossible for that UnitedBitcoin to replace the bitcoin because bitcoin itself is already an established currency and no one can beat it, but if that UnitedBitcoin proves its worth in the crypto world and can help too, i would gladly welcome it, but it can still never replace the Bitcoin.
United bitcoin just another fork coin from the bitcoin but it's not officially decided by the community and that was just another personal intention by the developer to issued the useless forkcoin to gain instant demand from the real bitcoin. It can be called the same with another altcoin. As you can see about the fact that it will never be replaced the bitcoin even the bitcoin cash fork was better than it can't replace the bitcoin too.
