Crypto currency seems to cold down these days
You are projecting unknown variables into something that does not need that variable. Being "Hot" does not mean its worth it every time. Being "Cold" does not necessarily mean its worthless.
and many people have lost faith in the past few months...
When did the opinion of some shitcoin bagholders start to make an impact on ther entire crypto economy?

People find most token are fake indeed, what they have was just a whitepaper.
I think most of them will die in the next year.
Ok so you are referring to shittokens. Well for those I am neutral because there are divided opinions. Your call.
But what about Bitcoin?
What about it? There is literally nothing to discuss because the price of a certain asset denotes the demand supply imbalance. Nothing more nothing less.
As the first and the most influential one, Bitcoin is still weak with numerous restrictions.
Like what exactly?
Maybe it will fall into the ground due to the political factors, or beaten by other token which is better.
Bitcoin has been made in such a way that it is censorship-resistant. I think thats what you were referring.

Only time will tells.
It already has dictated the demise of fiat.

In fact I am not quite understand the difference between Bitcoin and other coins, it seems that they can do the same thing.
