when the price was $2000 [...] even the marketcap was very low
You do realize that the market cap is just the price times the number of coins in existence, right? Of course the market cap will be lower when the price was lower.
Wow, are there still people who believe in that bitcoin will crash at some point?
I mean, it's happened before.
After the 2011 bubble (peak ~$30/BTC), we spent quite a few months in the single digits.
After the 2013 bubble (peak ~$1000/BTC), we spent over a year in the $250 neighborhood.
I would call those "crashes".
So why is a crash now unbelievable? Even a crash to $5000/BTC or so?
Doesn't mean that "Bitcoin is finished" or whatever. Just that the price is lower (comparatively) for a while.
if bitcoin crashes, another altcoin will replace it.
This much is probably true, even if only temporarily. The Ethereum price, f'rex, is growing pretty rapidly right now, even with other coins taking a bath. Bitcoin isn't the only game in town anymore, so even people getting out of one cryptocurrency can just move to another.
Thats true Bitcoin is not finished and that price is lower,But I believe and there are all precondition that price will be stable very soon.So peope said that This is hopeless situation and price will never be as much as it was,But why Miners in China cann't change the location? This will be good solution and I think it is theoretically possible.They can choose Countries wich have liberal approach about similar issues.for example Iceland,Germany,Georgia and others.So,Even in this difficult situation there are solutions and people must stop panic selling.
