You can't predict the market and you dont have to wait for bitcoin to drop to a particular price before buying Bitcoin. You can always buy Bitcoin so far as you are opportune to buy and if the market drop to the price that you have been anticipating for, then it is an opportunity to buy more Bitcoin.
As an Investor you have no business with predicting the price of Bitcoin because that's typically the hand work of traders and it is not easy to predict the price of Bitcoin because it is a volatile asset. Anyone who calls himself or herself an investor and is predicting the price of Bitcoin is really wasting time and this person will either sell before time or panic. To save one from the trauma that comes after predicting Bitcoin and didn't work, the person should accumulate Bitcoin and hold for a long term and stop wasting time and giving himself false hope as what they are predicting is not certain.
True, prediction really belongs more to traders than investors. As an investor, the main focus should just be on steady accumulation and patience. Bitcoin is too volatile for anyone to predict its exact moves, and most times people who keep trying end up either panicking or selling too early….
Long term holding has always proven to be the safer and more rewarding strategy. Instead of stressing over short term price action, it is better to just stick to the plan and trust the process..
