I see, this subject has been publishing in this forum over and over again. Actually, when Bitcoins price fall, every time people (newbie+ low skilled) assumed that Bitcoin will die. They actually dont have proper knowledge on crypto. Blockchains can grow forever, even if you stop a single node. Others will pop up and keep growing the blockchain. On the other hand, the real value of the crypto market is really incredible. From the recent decade, every time the price comes out higher than the past year. Only, this year might be an exception. But still, I can see long-term growth.
