A good investor must be a good calculated risk taker and must be very good in making strategist decision. Anyone that is waiting for Bitcoin to dip to his/her expected minimum level don't have investment mindset because Bitcoin is something that you may not possibly predict the minimum dip it will attain and as such while waiting for it to dip to your bench mark that you want to accumulate Bitcoin the price may appreciate unexpectedly beyond your target in such a way that you may not be able to strive in your investment.
If we trace back the record or history of Bitcoin price from 2010 till date you will be convince that Bitcoin is sometime that every potential investor should be confidence in making good investment without having double thought because irrespective of the volatility of Bitcoin price there is every indication that the value of Bitcoin will certainly appreciate beyond what we are seeing now in the future and good investors are making huge investment in Bitcoin and are making good returns on their investment especially those that have the strategy of holding it for long time.
I have been wondering what could possibly be your definition of a good calculated risk taker? Bitcoin investment is very much open in such a way that anyone can invest in his or her pacing, according to how much you can comfortably afford which differs from one to another, I don't see much of the calculated risk when you investing according to the size of you pocket after ensuring your basic needs are taken care with the mindset of making a provisional emergency funds, invest with an amount that you will not be needing for a long time, that way you can comfortably grow your asset with a peace of mind without ever considering that you are taken risk, because Bitcoin investment is really as risky as most people think it is.
