The time to buy was yesterday when the market was dipping. Now the price has gone up and there might be another dip very soon. Just look at what has been happenning in the past weeks.
I think this is still a time to buy because the price is still not too high, still the price of 9k, if seen from the price yesterday that semapat down till 7.9k and the highest price was 19k then it is now allowed to buy is still safe if for long
Yes, buying at the current price is also likely to get a profit if the benchmark price is 19k $. There is no harm in trying, bitcoin is very effective for long-term investment.
