Bitcoin appeared in 2009, eight years, the total value of the circulation of bitcoins up and down 200 billion US dollars. Bitcoin was declared "dead" by the media countless times. However, it is undeniable that the media has a huge influence. Therefore, with each media claim that "bitcoin is dead", the price of bitcoin will drop sharply. The magic is that every time Bitcoin is alive, its price has hit a new high all the way. In other words, in the face of so-called drug poisoning amateur media reports, bitcoin gradually developed "resistance", negative media coverage for the impact of bitcoin prices getting smaller and smaller. What will eventually destroy bitcoin? If there is a force that can destroy bitcoin, it must be human greed.
Investors can destroy Bitcoin and the current Crypto market. Investors are the ones who decide the survival of all, it will continue to exist as long as the investor, and it will disappear when investors abandon it to choose a new more potential.
You have some point here, if investors stop supporting bitcoin and focus to another project or another system that they think that will be much usable,
then bitcoin can be in doom, we know that it is a business where investors always looking for a big potentials to grow their investment, if they feel
unsafe with bitcoin then they will look for another investment to place their money, making a lots of negative effects including to complete failure of the chain, if worse come to worse and they stop using the chain.
