Bitcoin Booming

On Wednesday November 29, 2017, Bitcoin clipped the $11,000 mark as this crypto-currency reaches new heights every week. One year ago on Dec 1, 2016 Bitcoin stood at $753.25 and has increased 14x in that period. What are to make of this and what is next? Should you buy, sell or hold? If I knew the answer I would be a rich man, but with my limited brain power, I will stay away from this as in my opinion its an un-exploded bomb waiting to go off.
