I think the switch is confusing, unnecessary, and stupid. Most people aren't good at maths. They've heard of bitcoin, heard the price is going up and up, and then go to a site displaying the (m)btc price and see "$0.80 per mBTC'.

Any switch to mBTC should have been (a) agreed by the community and (b) implemented with an education program.

This adhoc approach  where some sites switch and others don't just leads to confusion.

Whether it contributed to the crash in the last 24 hrs or it was pure coincidence, who knows. What I do know is I don't believe in coincidence  

I also know that the bitcoin price was still doing great at "over $1000 a coin", people were still buying ........ mBTC is a damaging solution. to a non-existent problem.
