Is Bitcoin dead?

Hi,
I don t think is dead is just expensive ... i do not mine btcs becouse is hard but when i see he goes under 9k $ i buy some coins and then later i trade them when he goes up again ... till now i was able to make a few times nice profit .. when i buy under 9k and sell at rate 11k i make till now aways 23%-25% profit, but that was not so ofthen as i whished ...
