I wouldn't touch this coin with a ten foot pole as it seems to be directly trying to trick people into thinking its bitcoin. BTX is also used in stock markets to refer to bitcoin.

20 feet that's actually 6 metres. It would be really hard to get a grip in this thing trying to fend off nasty Bitcoin fork.
