i got into BTC when years ago it first hit $32.    then i watched it plummet down to around $3 or $4.  so %80 drops are not unusual.  if you have no faith in BTC why are you even here?    is your life so pathetic that you have to try to crap on everyone else's parade with your claims of scam and ponzi scheme?  we don't need your warnings.  we've been through these dips before.  ciao.
