Those people are just some dumbs who lost money due to joining the market in the all time high.
However, I don't agree with you that Bitcoin can be both a global currency and an alternative to Gold or Silver. It should be the one or the other.
Bitcoin will get banned if money laundering and ponzi increases from Bitcoin. Without centralization Bitcoin will not get legal status.
It will become legal but we need to wait exact time,to avoid this scam issues again we need to research first before we invest and don't trust with the investments with high returns because it is good to be true.
bitcoin is already legal on most countries and bitcoin wont also be banned even if we say that all bitcoin users will only use thier bitcoin for bad doings because bitcoin is uncontrollable at the first place . not all who uses bitcoin are fool or have a low iq except from the people that are get scamed not only once but twice or thrice .

bitcoin cant be call a global currency because some countries ban it but bitcoin is consider as an alternative to gold and silver because bitcoin can do what gold and silver can do .
