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.
You do not think this is cheap, I kind of agree, I think it will still drop a bit more,,, and we can even have many more drops this year and in 2020, before we see BTC at 10k again. On the other hand, I am not waiting for price drops, I am getting as much as I can and whenever I can. I read too many posts of people saying $30 was too expensive or $100 was the most it would ever be.
