Bitcoin is $ 8,000 right now and I don't think it's cheap, it's possible that Bitcoin will go down again because people who make a profit from Bitcoin will sell their bitcoins. In this case, you need to wait a bit longer to buy Bitcoin.
That is what is currently happening in the market right now and people should wait until the market pull back a little before buying again. It is like bitcoin is at the over bought area and that is why it could not gather strong momentum to break $8500 last week.
