I think Bitcoin's price will fall sharply one day, but that doesn't mean the cryptocurrency is doomed to But it has a big effect in crpto currencies if bitcoin crashes .. It only have 21 millionth bitcoin that are circulate in the world and currently 12 million are already used ..if they reach the max circulation it also affect the crypto world and the worst btc will destroy it also affects altcoins because btc is the main reason why crypto are popular.
Where are you seeing the altcoins don't get doomed caused by the bitcoin? The fact majority of altcoin gets dumped a lot. What the heck about 12 million already used? The circulating supply was around 16.7 million.
if you can't argue about the fact and it will better for you to don't spread another bullshit to the newbies. It's very clear that you are not knowing anything about the crypto rather than write another bullshit that makes others scared with your opinion.
