Buy buy buy, regardless of the price as long as you can afford it, investors waiting solely for a dip to buy aren't real investors, they are more traders than investors, this is because a trader would want to make profit as quickly as possible, naturally an investor wantieto make profit as quickly as possible too isn't necessarily wrong but they also consider the long term gain to be made, traders don't consider this, they are all about what to get out of the business now not what they will get from it later.
Those who buy when the price is falling are also good even if you call them traders. You also don't forget that they will be worthy of being called investors who are playing a strategy in getting Bitcoin in large quantities when the price is falling so that when the price has increased they can buy in small amounts.
If accumulated, then they are the winners.
At first glance there is no difference between traders and Bitcoin investors. Traders buy at a decline will sell at a rising price and from the profits obtained can be prepared to buy again later.
