Its far from a bubble until McDonalds, Walmart, and Gas Stations begin to accept bitcoin......
Untill then, we have a long ways to go!
Buy and hold is my advice.
Buying bitcoin at this price requires you to be a big time investor and the price of bitcoin is on a bubble because there are big funds coming from big time investors and wall street and hence i do think we will see a big correction soon,as these investors might dump the coin and can manipulate the price ,so be cautious .
