7k usd is still pretty small to some people therfor they did not consider the increase as a bull run   . for them a real bull run is when the price cross to 18k to 20k usd just like what happened last two years ago  .  when it comes to buying/investing , it also depends on the user if he thinks that he can afford the current price then he must buy now but if not then its better if he can wait for more price decline  .  price of bitcoin is not really that huge , so id say that its not yet late to join  the ride  .
